any plans on an async interface?

Hi! I'm curious if there is any intention of adding an async/await interface to this library. The docs say "For blocking usage, use BlockStore", which I read as there might be.

I'm not sure if this would make any sense building on top of rusqlite, but I thought I would ask. An alternative I was looking at was `iroh`, which seems to have an async blockstore internally, built on RocksDB. But that project has not published any crates yet, and does not seem as mature as this one, at the present moment.

The project i'm currently working on is an implementation of the bluesky atproto "personal data server", which needs a blockstore. I've gotten things working with a blocking API, but it feels like the sort of project/service which would benefit from async networking and I/O.
