/**
 * Properties used by {@link Source} for data processing.
 *
 * @typedef {object} SourceProperties
 * @property {string} id - Identifier prepended to console output.
 * @property {SourceFile|SourceFile[]} data - Data file(s).
 * @property {string} vfs - GDAL virtual file system type (`/vsizip/`).
 * @property {string} filename - Relative path to the file to open with GDAL
 * within an archive file.
 * @property {string} layer - Layer name to open with GDAL within a file. Only
 * relevant for files with multiple layers.
 * @property {function} openFunc - Function that takes a file path (or array)
 * and returns a GDAL dataset. If provided, takes precedence over `vfs` and
 * `filename`.
 * @property {object} geometry - Geometry field names for formats without
 * explicit geometries (e.g. CSV). If not provided, will
 * attempt to guess from field names.
 * @property {string} geometry.wkt - Name of field with well-known-text (wkt)
 * geometry. If provided, takes precedence over `x` and `y`.
 * @property {string} geometry.x - Name of field with x coordinate (longitude,
 * easting).
 * @property {string} geometry.y - Name of field with y coordinate (latitude,
 * northing).
 * @property {string} srs - Spatial reference system in any format supported by
 * [OGRSpatialReference.SetFromUserInput()](https://gdal.org/api/ogrspatialref.html#classOGRSpatialReference_1aec3c6a49533fe457ddc763d699ff8796).
 * @property {Object.<string, Object.<string, string|Object.<string, string>>>} codes -
 * Labels for coded values in the data. Each initial key is the field name,
 * followed by a mapping of coded values to labels. The label can be a string or
 * an object, in which case the keys are new field names and the values are their values
 * (e.g. `{oldField: {ab: {newField1: 'a', newField2: 'b'}}}`). The new field names are
 * added to the old field name with a period (e.g. `oldField.newField1`).
 * @property {Object.<string, string|function>} crosswalk - Crosswalk mapping to
 * a target schema. For each `key: value` pair, `key` is the new field name and
 * `value` is either the old field name (e.g. `height: 'HEIGHT'`) or a function
 * that takes an object (of feature field values) and returns a value (e.g.
 * `height: x => x['HEIGHT'] / 100`).
 * @property {function} coordsFunc - Function that takes an object (of feature
 * field values before the crosswalk) and returns a number array of point
 * coordinates `[x, y]`. This is a useful alternative to `geometry` if the
 * coordinates need to be extracted from field values (e.g. `obj =>
 * obj.XY.split(';').map(Number)`).
 * @property {function} addressFunc - Function that takes an object (of feature
 * field values before the crosswalk) and returns an address string for
 * geocoding.
 * @property {function} deleteFunc - Function that takes an object (of feature
 * field values before the crosswalk) and returns a value (e.g. `x =>
 * x['HEALTH'] === 'dead'`). The feature is excluded from the output if the
 * returned value evaluates to `true`.
 * @property {SourceFile|SourceFile[]} metadata - Metadata webpage(s) or
 * file(s).
 * @property {object} license - Data license.
 * @property {string} license.id - License identifier (see `./lib/licenses.js`).
 * @property {string} license.name - License name. Only provide if `id` is not.
 * @property {string} license.url - License URL. Only provide if `id` is not.
