- Remove unused `MilliSeconds`, `MicroSeconds`, and `NanoSeconds` types - Remove `Bps`, `KiloHertz`, and `MegaHertz` types that were only used for converting to `Hertz` - Replace all instances of `impl Into<Hertz>` with `Hertz` - Add `hz`, `khz`, and `mhz` methods to `Hertz`, as well as free function shortcuts - Remove `U32Ext` extension trait
