v2alpha1: Add malfeasance API

[kacpersaw]

message MalfeasanceProof {
    bytes smesher = 1;
    uint32 layer = 2;
    enum MalfeasanceType {
        MALFEASANCE_UNSPECIFIED = 0;

}

Add malfeasance services to v2alpha1

This API will change a lot with changes in the near future:

• Malfeasance proofs will not have a layer identifier any more but instead a version identifier.
• There are now 3 domains for each proof:
  • Activation
  • Ballots
  • Hare
• Each domain can have any amount of sub-types of proofs. For Ballots and Hare at the moment there will only be a double publish proof, activation will have at least 5 sub-types.
  • The proof itself is wrapped in layers - the actual proof, wrapped in a domain-specific layer, wrapped in a general layer. The bytes returned however should in my opinion only be the concrete proof and not the wrapping layers.

For reference see also this these tickets:

• Malfeasance V2: Double Post go-spacemesh#6140
• Malfeasance V2: Invalid Post go-spacemesh#6141
• ... to be continued (I'm still creating issues 🙂 )
