v0.7.5

This is a bigger patch release, but there are several improvements on develop that should be on master already, and v0.8.0 is still some time away.

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)
