feat: Batching

[mrousavy]

const storage = new MMKV()

storage.batch((s) => {
  s.set('hello', 'world')
  s.set('test', 'another')
  s.set('someLargeBuffer', buffer)
})

Love the feature!
I've been playing with the library lately for https://github.com/Expensify/App and have a quick question - as far as I understand this will trigger addOnValueChangedListener for each updated key (20k keys when eg. populating will do 20k events etc), do you think it might be worth to have a separate listener notifying about the batched updates being applied? Like a addOnBatchedValuesChangedListener 😅 that will trigger only once.

Hey - yea for listeners we should maybe batch that as well then. 🤔
