Geometrical and kinematical Kikuchi pattern simulations for all point groups

[hakonanes]

Description of the change

This PR contains much new functionality, mainly a new kikuchipy.simulations.KikuchiPatternSimulator class for

1. Correct geometrical simulations for all point groups using the new ReciprocalLatticeVector class in diffsims (replacing kikuchipy.generators.EBSDSimulationGenerator)
2. Kinematical simulations returning an EBSDMasterPattern

I have to get this released before a workshop at NTNU, so there will only be the bare minimum of documentation and tests.

Fixes: #507, #506, #487.

Progress of the PR

• Docstrings for all functions
• Unit tests with pytest for all lines
• Clean code style by running black via pre-commit
• Deprecate kikuchipy.generators.EBSDSimulationGenerator
• Test new KikuchiPatternSimulator class
• Test new GeometricalKikuchiPatternSimulation class
• Update simulations notebook
• Perhaps add conversion from stereographic projection to Lambert projection so that one can project part of the kinematical master patterns to the detector (generate an "EBSD pattern")
