Cjio

Changed
- now CityJSON v2.0 is the default version
- fixes for gltf export
- fix the cjio subset and children
Added
- added an upgrade ops for v2.0 files

Changed
- Removed the emojis in the console output for the function 'info'

Added
- Added the `translate` paramter to `cityjson.compress` to manually set the tranlation properties instead of computing from the data.
- The `cityjson.cityjson_for_features` and `cityjson.generate_features` methods.

Changed
gltf (glb) converter
- `to_glb` sets a root transformation matrix for z-up to y-up, instead of swapping the vertex coordinates directly.
- Takes a `do_triangulate` argument to completely skip triangulation.
- Compute (smooth) normals.

Added
- added functions for reading/writing CityJSONL (CityJSONFeatures) from stdin/stdout, so cjio can be part of a pipeline of operators processing 3D city models 🚀
Changed
- many small bugs fixed
- The function that used an API are going to be deprecated in the upcoming releases, because the cjio API is under refactoring. The affected functions are `cityjson.save`, `cityjson.load`, `cityjson.save`, `cityjson.load_from_j`, `cityjson.get_cityobjects`, `cityjson.set_cityobjects`, `cityjson.to_dataframe`, `cityjson.reference_geometry`, `cityjson.add_to_j` and all members of the `cityjson.models` module. There is a new cityjson library under development, called cjlib, which will replace the relevant parts in cjio.

Changed
- cjvalpy >=v0.3 is required to use the latest schemas (v1.1.2)
- fix the parsing of the validation string

Added
- Subset more than one CityObject type (9)
- `models.Geometry.reproject()` for reprojecting dereferenced geometry boundaries
- Read from `stdin` and save to `stdout`
- `--suppress_msg` to suppress all messages. Required when saving to `stdout`
Fixed
- Subset with BBOX does not modify the input model anymore (10)
- `cityjson.load()` does not fail on a `GeometryInstance`, however it does not load it either (19)
- Fixes to the *glb* exporter (20, 57, 83), and fixed the coordinate system
- `texture` and `material` are correctly removed from the geometries of the CityObjects with `textures/materials_remove`
- `vertex-texture` is removed from the CityJSON with `textures_remove`
- Docker image build (77, 132)
- Other minor fixes
Changed
- Export format is an argument, not an option (35), e.g. `cjio ... export obj out.obj`
- NumPy is a hard requirement
- Require pyproj >= 3.0.0 (142)
- Refactor warnings and alert printing (143)
