Add physical timers support

[Hyuriin]

This is the best cubing timer for mobile, but this is my unique suggestion: add support for timers, like qiyi timer, qiyi smart timer or gan timer, for example, that have cable or bluetooth function. All of them timers have an app, but sincerally, these apps are horrible than twisty timer. Consider this suggestion, please :)

Checkout Cubic Timer: https://github.com/hato-ya/CubicTimer

It's a fork of Twisty Timer with support for physical timers. You can easily export a backup from Twisty Timer and import it in Cubic Timer. Works great for me 👍
