Read GeoJson files as UTF-8 regardless of locale (#2331)

GeoJson(filename) opened the file in text mode without an encoding, so
it was decoded with the locale encoding. On Windows that garbles or
fails on non-ASCII properties (the bundled kuntarajat.geojson raises
UnicodeDecodeError under cp932). Read the file as bytes and let json
detect the encoding, which also accepts a UTF-8 BOM.

Bump actions/checkout from 7.0.0 to 7.0.1 in the github-actions group

Issue 1359 (#2159)

* Fix for issue 1359

This includes a structural change. I added a Class object with
a include method. This follows leaflet's `L.Class.include`
statement. This allows users to override Leaflet class behavior.

The motivating example for this can be found in the added
`test_include` in `test_map.py`. Using an include, users can
override the `createTile` method of `L.TileLayer` and add
a headers.

* Close #1359

Add an include statement, that will allow users to override
specific methods at Leaflet level. This allows users to customize
the "createTile" method using a JsCode object.

* Add documentation
