Bson has added decimal support and this crate can use it.

Context

The bson crate was pinned to a branch on a fork of rust-bson. This fork has fallen behind, and my PR is updating to the released bson crate.

I am not able to have the most recent version since it doesn't have a wasm compiling Decimal128 implementation. If I remember correctly, bson-rust crate will have it in relatively soon, the team is just working on getting async stuff in first.

Ah, that makes sense. Though it might not help, would you be open to feature-gating the wasm support? I'm exploring writing a mongo connector for a dataframe crate I'm writing, so schema inference becomes important. In the short term I could do without the inference, but if what I'm building becomes useful to people, that need would arise.

Hmmm, I think we should be okay putting wasm under a feature flag. Let me try and play around with the cargo toml and see if I can get everything to compile properly!
