Big feature/breaking release to implement support for DM v2/CM v4.x metadata. Now properly parses/writes metadata blocks for both display management metadata versions.

Supported metadata levels:

• DM v1 (CM v2.9): L1, L2, L4, L5, L6
• DM v2 (CM v4.x): L3, L8, L9, L10, L11, L254

Important changes:

Generator

• Implemented proper support for L3, L8 and L9 metadata for RPU generation from XML.
• Improved the template to allow more flexibility. Now allows specifying shots (with per-shot or per-frame metadata blocks).
• Refer to documentation and example.

Editor

• Added convert_to_cmv4 option to convert an existing RPU to DM v2, defaulting to adding L11 metadata.
• It is now possible to remove polynomial/MMR mapping from the RPU using remove_mapping
• Refer to documentation and examples.
• For L11, see convert_to_cmv4 example.

Exported JSON from info or export now have DM metadata split in two objects:

• cmv29_metadata and cmv40_metadata, which have the same structure: a number of blocks, and list of blocks.

For the C API, see changelog.
