rich text: Optionally return cursor position from dry run & allow indenting text

The goal of the changes made in this PR is to create something with this
effect ("Jonko" is in in green, the rest is in white):

    "Dear god." Jonko quickly replied,
    crestfallen.

In order to do this, I need to call `NE_RichTextRender3D` or
`NE_RichTextRender3DAlpha` three times: once to draw the first part of
the sentence with the white font, once to draw "Jonko" in turquoise, and
once to draw the remainder of the sentence in white again. In order to
ensure that text is being drawn in the correct location, I need the
position where the previous call stopped drawing, which leads to the
first change this PR makes: I have added a version of
`DSF_StringRenderDryRun` which accepts pointers to `final_x` and
`final_y` and stores the last position of `font->pointer_x` and
`font->pointer_y` in them and I have added a new variant of
`NE_RichTextRenderDryRun` called `NE_RichTextRenderDryRunWithPos` which
uses that DSF function and has analogous parameters.

These functions get us the position where we need to place the next
cursor, but the next issue is that currently NitroEngine and libDSF only
allow for specifying the position of the overall box to draw text in,
but not where to offset the cursor in that box. This leads to the
following problem ("Jonko" is in in green, the rest is in white):

    "Dear god." Jonko quickly replied,
                        crestfallen.

Thus, the second change: I have introduced new versions of
`DSF_StringRender3D` and `DSF_StringRender3DAlpha` which accept an
`xStart` position that is added to the `pointerX`. Correspondingly, I
have added versions of `NE_RichTextRender3D` and
`NE_RichTextRender3DAlpha` that use these new functions as well.

Let me know if there are any issues with how I've written this (C is not
my forte, after all), but the first screenshot is this being tested in
production code.

 Changelog
 =========
 
+Version 0.15.3 (2025-03-26)
+---------------------------
+
+- The devkitARM makefiles have been removed as they only work with old versions
+  of devkitARM, which aren't supported by its maintainers. The code and examples
+  of Nitro Engine will probably need changes to work with current devkitARM.
+- The GRF files used in an example have been updated, they were built before the
+  format was changed.
+- The build scripts for assets have been modified to use the value of the
+  environment variables ``BLOCKSDS`` and ``BLOCKSDSEXT`` if they are found.
+- Build library with debug symbols to help debug applications that use it.
+
+Version 0.15.2 (2025-01-15)
+---------------------------
+
+- Fix `ar` binary used to build the library.
+- Update documentation.
+- Fix build of examples in devkitARM.
+- Improve setup instructions.
+
+Version 0.15.1 (2024-12-23)
+---------------------------
+
+- Install licenses with the rest of the library.
+- Clarify some comments in examples.
+
+Version 0.15.0 (2024-12-01)
+---------------------------
+
+- Allow users to specify the transformation matrix of a model manually.
+- Fix a devkitARM Makefile in an example.
+
+Version 0.14.0 (2024-09-10)
+---------------------------
+
+- Use ``stdint.h`` types instead of libnds types.
+- Update BlocksDS makefiles.
+- Update libdsf to v0.1.3.
+- Fix some memory leaks/use-after-free bugs in the RichText module.
+
+Version 0.13.0 (2024-06-08)
+---------------------------
+
+- Define BlocksDS as the main toolchain to use with Nitro Engine.
+- Simplify build and installation instructions of the library.
+- Update ``md5_2_dsma`` to correctly export the base animation of models.
+- Stop using ``NE_RGB5`` in the examples, this format is discouraged.
+- Optimize copy of ``NE_RGB5`` textures to VRAM.
+
+Version 0.12.0 (2024-03-30)
+---------------------------
+
+- Deprecate ``NE_ShadingEnable()``. The name was misleading. All examples that
+  use it have stopped calling it.
+- For sprites, add a way to specify texture coordinates inside the material to
+  use a small part of the texture instead of the whole texture:
+  ``NE_SpriteSetMaterialCanvas()``. This is now used in the sprites example.
+- Stop using global variables in most examples. Instead, the rendering functions
+  get values through the arguments of ``NE_ProcessArg()`` and
+  ``NE_ProcessDualArg()``.
+- Don't expect palette objects when loading GRF files if the file doesn't
+  contain a palette.
+- Allow loading BMFont fonts from RAM, not just nitroFS. Add an example of
+  using rich text fonts from RAM.
+- Added a function to reset the rich text font system. Also add a function to
+  return the size that a specific text string would have if drawn.
+- Add shadow volume example.
+- Build some functions that do lots of multiplications as ARM to increase
+  performance.
+- Fix compilation with devkitARM.
+- Fix linker invocation for C++ with BlocksDS.
+- Update libDSF to version 0.1.2, with some speed improvements.
+- Relicensed libDSF under "Zlib OR MIT" to simplify licensing with Nitro Engine.
+- Some minor documentation improvements.
+
