Thanks!

@VictorKoenders thank you! With this change I managed to successfully port all my code to bincode 2.0. I use bincode extensively for networking and a custom file format, and everything seems to work well and is backwards compatible with 1.x.

I'm okay with having git dependencies and I'm in no rush, but would appreciate 2.0.0-rc.2 at some point :)

Edit: as a bonus, without serde Wasm build of my client is now 20kb smaller 🎉.
