Create new Wasm binary hashing mechanism

[lastmjs]

Because of dynamic module loading, binary hash checking of Kybra canisters won't give the same benefits or guarantess as Rust/Motoko/Azle binary hashes. We'll need to come up with mechanisms to fix this.

• Keep in mind that with Kybra, the binary hash will basically be useless, as much of the actual code/functionality will change and not be in the binary. Perhaps we could send the Python source code up in the binary to help with this?
• We could probably hash all source code and include the hash in the binary though

This shouldn't be a problem anymore, except for the python stdlib. Only on first deploy will the stdlib be a part of the binary, so the hash will change on subsequent deploys. This is a much simpler problem now
