feature request: option to disable document normalization on editor initialization

slate editor constructor includes:

    // Run `onChange` on the passed-in value because we need to ensure that it
    // is normalized, and queue the resulting change.
    const change = props.value.change()
    stack.run('onChange', change, this)
    this.queueChange(change)
    this.state.value = change.value

While this is great in general, when dealing with big, complex documents, the normalization of the all document can be very long (a few seconds). It would be awesome if we can add an option prop that disable the initial value validation/normalisation. Obviously, in this case, the responsibility of ensuring the supplied value it valid moves to the developer.

Is this documented anywhere on https://docs.slatejs.org/ I couldn’t really find anything relevant when searching for “normalize”.

Also, is there a utility function to normalize a document, ideally without a whole editor instance e.g. for passing a normalized document to the editor while normalize: false is set?

Would definitely appreciate this option, as mentioned normalization can hang the browser window for a few seconds. If I can guarantee that the content was previously saved out of Slate then this step seems like it could be skipped for a better user experience.
