Replace Bincode with Postcard

[ranile]

Postcard was chosen because it is recommended by the bincode current readme and uses serde instead of custom serialization/deserialization protocol

fixes #529

The breakage is removing the public Bincode type. Anyone who explicitly wrote:

use gloo_worker::Bincode;

WorkerSpawner<MyWorker, Bincode>

will get a compile error. But in practice, I think nobody does this.

The whole point of the CODEC = Bincode default type parameter is that users never name it.

Looks good!

I think it's worth mentioning.

I agree, I'll edit the PR description so anyone following the changelog can see it and include it in commit too

Need to edit the version of the root gloo crate in the CHANGELOG to 0.13.0 now though

I'll just let the tool from #542 re-generate it
