Ipl3checksum

Added

- `CICKind.get_entrypoint`: Returns the entrypoint address that would be used
on runtime.
- `CICKind.calculate_checksum`: Convinience method that wraps
`checksum::calculate_checksum`.
- Python bindings:
- Expose `Ipl3ChecksumError` to Python as a new exception for each error of
the enum. Refer to `ipl3checksum.exceptions`.

Fixed

- Python bindings:
- Fix `detectCIC` and `detect_cic_raw` functions not accepting `bytearray`
objects.
- Fix some typos

Added

- Add Rust support.
- New static methods for `CICKind`.
- `CICKind.fromHashMd5`: Returns a CIC kind based on the passed md5 hash.
- `CICKind.fromName`: Returns a CIC kind based a string representing its name.
- Add C bindings.
- Add support for the IPL3 5101 variant (Used by Aleck 64 games).
- New frontends:
- `check`: Checks if the checksum in the ROM matches the calculated one.
- `detect_cic`: Allows to detect the cic type used by a rom.
- `sum`: Calculates the ipl3 checksum of a rom.
