Test format: BLS hash-compressed

A BLS compressed-hash to G2.

Test case format

The test data is declared in a data.yaml file:

input: 
  message: bytes32
  domain: bytes8   -- the BLS domain
output: List[bytes48] -- length of two

All byte(s) fields are encoded as strings, hexadecimal encoding, prefixed with 0x.

Condition

The msg_hash_g2_compressed handler should hash the message, with the given domain, to G2 with compression, and the result should match the expected output.
