Release v2022.01.11

[vespakoen]

• Changes FindPython to FindPython3, because I couldn't get FindPython to play nice with conda-build.
• Disables BUILD_DOC when building the Python library
• Fixes issue with VERSION_STRING, it could not be passed as a CMake option, because the default was set to a boolean value, which could not be changed to a string.
• Adds LANGUAGES to CMake's project() definition
• Use sscanf on unix platforms in STLReader (speeds up the STLReader a whole lot)
• Use RelWithDebInfo for release builds, and add .dSYM file on macOS for source mapping and better debugging support.
• Enable link time optimization
• Zip CXX libraries before release (I had to add them manually before)
• Add custom delocate script on macOS, and prefer system OpenMP before loading the bundled one.
• Use current date as version in development builds
