Support component versioning

[mdingena]

Context

After a recent game update, decoding strings stopped working. This is because the Pickup component has been updated to contain additional data. These strings contained that data but the Pickup decoder did not read it properly, causing bit misalignment.

Strings come with component versioning. The transcoder was already writing this component versioning after encoding, but decoding doesn't handle any of that; it always assumes the version it knows is the version we're getting from the game.

Changes

• Added a version parsing function.
• Added version support to each component, allowing the decoders to conditionally read data from the string depending on which version component it's getting.
