feat: added skippedOrigins option

[LuckyOneDev]

This option is needed in cases where you want to track custom transaction origin when using mutative-yjs to update doc. For example:

    this.undoManager = new Y.UndoManager(scope, {
      trackedOrigins: new Set([MY_ORIGIN]),
      captureTimeout: 1000,
    });

Proposed syntax:

    const binder = bind(ydoc.getMap(), {
      skippedOrigins: [MY_ORIGIN],
    });

Since this PR has been delayed, I'll merge it first and address the necessary fixes in a follow-up.

hi @LuckyOneDev, thanks for the PR and for explaining the Y.UndoManager.trackedOrigins use case.

I merged this and added some follow-up fixes around nested transactions, multi-binder sync, structural sharing, and Set support for skippedOrigins.

This is now released in mutative-yjs@0.3.0.
