[IndexedDB] Feature Request: Allow batch adding records (from an Array) (#69)

I'm not sure if this follows the correct procedure for feature requets, but here I go.

I recently had the issue that I wanted to fill an indexedDB (initially) with a very large Array of Objects. However looping through the Array and adding the Objects one by one was very efficient. Wouldn't it make sense to have an equivalent of `getAll()` with adding Records?
