Update byte serialization in bindings

[piotr-roslaniec]

• Refers to Use static arrays for serialization of arkworks primitives #101
• Renames dkg.final_key to dkg.public_key in Python & WASM bindings
• Ensures that the DkgPublicKey is serialized to bytes without extra u8 denoting Vec<u8> length, using a GenericArray instead
• Expose DkgPublicKey.serialized_size

@derekpierre Are there any other places where removing serialization overhead (u8) matters?

• I thought I remembered you mentioned potentially changing the serialization for Transcripts as well. Was that done already/still planned to be done? Reducing the size of anything added to the Coordinator helps to keep gas prices down.
• Did you add the serialized_size() method after 0.1.10 was published? I don't see it.

@derekpierre Transcript has a variable length (depending on the size of the ritual) and so I'm unable to make any improvements there.
I just published ferveo-py@0.1.11 which exposed serialized_size.

Great. Thanks!
