Feat/render queue

[Pouf]

• Addition of RenderQueue, RenderQueueItem and OutputModule models
• Parsing of render queue, render queue items (and settings), output modules (and settings)
• Easier acces to chunk attributes by monkey-patching __getattr__: chunk.data.attr -> chunk.attr
• Monkey-patching for chunk type is now dynamic and does not need to be updated when adding new chunk types
• Update to kaitai 0.11
• Bump version from 0.0.4 to 0.1.0
• Add mypy github action
• Add py3.7 test github action
• Improve docs
• Add rudimentary (⚠ WIP, breaking changes will happen) output module preferences parsing and model
• Remove most enums from kaitai file to avoid double maintenance
• Simplify binary to enum mappings
• Renamed some attributes to simplify and match Extendscript (folder.folder_items -> layer.items, project.project_items -> project.items, item.item_id -> item.id, ...)
• Most items (project, compositions, folder, layers, ...) now have their parent / childs available to them, instead of just their ids. This allows to write layer.parent instead of project.items[layer.parent_id].
• Improved version parsing thanks to https://github.com/tinogithub/aftereffects-version-check
• Improved and simplified property and effects parsing (still WIP)
• raise instead of return None in kaitai.utils._find_chunk and kaitai.utils.find_by_type to avoid union types (Aep.Chunk | None) and assert chunk is not None everywhere
