This changes the way how the mattes are stored in the compositor node. This used to be a single string what was decoded/encoded when needed. The new data structure stores all entries in `CryptomatteEntry` and is converted to the old `matte_id` property on the fly. This is done for some future changes in the workflow where a more structured approach leads to less confusing and easier to read code.
