Moved the documentation to a separate docs directory. Added more examples for use with generate subcommand.

Bug fixes

• Issue #91: Fixed regression to allow users adding L2 metadata when generating.
• Issue #97 (fix by @nekno): Improved output file name when using convert subcommand to reflect the presence of EL/RPU better.
• Improved generator config JSON default values to not error unnecessarily.

Features

• Added the possibility to specify any default metadata block levels to be used for the whole sequence when generating RPUs.
• Added a way to edit per-shot/per-frame metadata even when generating from HDR10+ or madVR measurement files.
