PyFLP 2.0.0

[demberto]

PyFLP 2.0.0 has been released.

PyFLP has been rewritten.

Highlights:

1. Richer events: Variable data events now parse their structure themselves.
   Fixed size events are categorized closely to the data they represent.
2. Lazy evaluation: Properties are evaluated as lazily as possible to prevent
   the use of private variables and keep them synced with event data.
3. Neatly organised models: Appropriate use of composition and subclassing.
4. Zero pre-parse field validation: Makes sense for an undocumented format.
5. Fully type hinted: Ensures strict adherence with pyright.
6. Simplified single-level module hierarchy to ease imports.
7. Docs now contain images for corresponding model types.
