Add LevelDB, IndexedDB, LocalStorage and SessionStorage

[JSCU-CNI]

This PR adds a LevelDB storage implementation to dissect.database.

Also adds support for serialization formats building on top of LevelDB: IndexedDB, and Chromium's LocalStorage and SessionStorage. Please let us know if these formats should be structured differently in this project.

Makes use of two (pure Python and/or Rust) dependencies: cramjam (for LevelDB Snappy decompression) and v8serialize (for IndexedDB v8 javascript object deserialization). We do not have the time or resources to port these dependencies to dissect.util or dissect.* - hopefully these dependencies can be accepted.

If you could clone me, that'd be great.

Unfortunately this is a huge PR and I simply have not gotten around to looking at it yet. Between reviewing all other PRs and working on large PRs myself, too, I'm simply stretched thin.
What could help is if you could provide me with a prioritization of PRs from your side, so I can look at them in that order.

How you doin'? There's a lot of unnecessary patterns in here (class level type hints for no apparent reason, methods that could easily be inlined or more easily replaced by inheritance, you can take my comments on that in the earlier files as generic comments over the rest as well (it's very slow to review a large PR on GitHub).

I think ideally we maybe have our own version of the v8 deserialization. Since we mostly care about deserializing and not so much roundtripping, I think we could make a much more simplified version that just maps to native Python types (a little bit similar to how we deserialize NSKeyedArchiver plists).

Since we don't have a dissect.serialize or similar just yet (I don't want to create one before the monorepo), perhaps it could just live in dissect.util.

I probably am drastically oversimplifying this, so maybe you could give me a reality check. v8serialize is at least pure Python, so I'm also fine with just keeping the dependency on it for now, with having our own being a longer term goal.
