transaction support in Elf

[Dimonina]

Hi man. Thank you for the Elf library. I'm planning to migrate from Akita, but a couple if things are still unclear to me.

1. To prevent a lot of emits from stores, we had to use combineQueries instead of combineLatest. How can we do it in Elf now?
   combineQueries([elfStore1.pipe(...), elfStore2.pipe(...)]
2. Is it possible to implement applyTransaction in Elf to do an atomic operation on writing to stores, rather then use combineQueries at the selection phase of the data flow?
   applyTransaction(() => { elfStore1.update(...); elfStore2.update(...) })
3. Yep, and what about logAction('do smth')?

Thank you <3

• combineQueries is an alias for combineLatest with auditTime(0). You can create it on your own if you need it.
• applyTransaction is primarily used to batch multiple updates of the same store into one emission. Since the update method accepts multiple reducers, this isn't needed:

store.update(
  addEntities(),
  updateProp(),
  ...
)

• We can expose a send function, but it'll not replace the current update log.
