IndexedDbFileSystem class final

A file system storing files divided into blocks in an IndexedDB database.

As sqlite3's file system is synchronous and IndexedDB isn't, no guarantees on durability can be made. Instead, file changes are written at some point after the database is changed. However you can wait for changes manually with flush

In the future, we may want to store individual blocks instead.
