[v2] new implementation with useMutableSource

[dai-shi]

• separate proxy-compare as a dependency done in v1.5
• new implementation with useMutableSource in the RFC
• in TypeScript done in v1.5
• mode=0 by default (breaking change in behavior) done in v1.5

Check list:

• implementation
• readme
• docs
• better to use batchedUpdates?

There's still something I would like to investigate.
Currently, it's failing "check 3" in https://github.com/dai-shi/will-this-react-global-state-work-in-concurrent-mode, because render interruptions take more time (avg 800ms > 300ms).

One of the e2e tests failed with a weird behavior in 07_todolist. Downgrading react experimental fixes it... 0.0.0-experimental-d7382b6c4
Let's wait for upstream to fix it...

Let me close this for now because:

• uMS is not likely to be landed soon.
• since v1.5, react-tracked depends on use-context-selector and not much is required to support uMS in this repo.
• we hope some better primitive hooks for react state instead of uMS.
