onDelete, onRemove or onRemoveBlocks event handler

[coxato]

Is your feature request related to a problem? Please describe.
I would like to have a specific event handler when a block or blocks are deleted, because I have some linked blocks that are being added as pairs, e.g (startBlock and endBlock) so if I delete a startBlock the endBlock is automatically deleted, because they are "pairs" in my implementation.
So I don't want to do that validation on the onChange method every time.

Describe the solution you'd like
Having a onDelete or onRemove or onContentDeleted or onRemoveBlocks event, so it receives a callback with the deleted blocks[] as argument.
something like this:

  const editor = useCreateBlockNote();

  useEffect(() => {
    if(editor){
      // a function to know when blocks are deleted so we don't use onChange every time  
      editor.onRemoveBlocks((deletedBlocksArray) => {
        myCustomHandler(deletedBlocksArray);
      })
    }
  }, [editor]);

Describe alternatives you've considered
Right now I do a validation for ALL the blocks on every onChange, but I think isn't the best approach, I would like to do those validations only when a block is deleted, if we are editing or creating/adding blocks I don't need to do extra validations.

is there any other possible solution?
