Poor insertion performance when using multiEntry about fakeindexeddb HOT 1 OPEN

I think the problem is that each object store and index is just an array. That makes inserting and deleting objects very slow. Also it's pretty slow for retrieving and updating objects. You know, it's almost as if there are reasons real databases use less stupid data structures :)

Multi entry indexes with a lot of keys, that's gonna be a problem.

For a long time I've wanted to address this, but never got around to it. I'm not sure when I will, although I probably should soon cause I've used many of your libraries and learned a lot from your code. No promises though :)

If you or anyone else feels like taking a stab at it, I think it should be possible to do by just editing https://github.com/dumbmatter/fakeIndexedDB/blob/0fd26fe2c91eecee58a2d48e48cf60ea93c2e9e7/src/lib/RecordStore.ts - replace the stupid array implementation with a B-tree or whatever.
