* Disabled `avoid-breaking-exported-api` and sorted items in Clippy.toml
* Renamed `BSD` -> `Bsd`, `SYSV` -> `SysV`, and `CRC` -> `Crc` to match Rust naming rules
* Renamed items in `BackupMode` and `UpdateMode` because they repeated the same word in every item - making it redundant and harder to read
