• Customized backspacing behaviour: signs that are encoded as sequences, such as 𒋛𒀀 or 𒊩𒆳, are backspaced atomically if they are composed atomically. See the relevant section of the readme.
• Added macOS support.

Thanks to @PeterConstable for pointing out that the Text Services Framework provides APIs that make it easy to backspace sequences as they are emitted.

Thanks to Pavla Rosenstein and @erica-scarpa for testing and providing feedback on early prototypes of the macOS version.
