Test format: BLS signature aggregation

A BLS signature aggregation combines a series of signatures into a single signature.

Test case format

input: List[BLS Signature] -- list of input BLS signatures
output: BLS Signature -- expected output, single BLS signature

BLS Signature here is encoded as a string: hexadecimal encoding of 96 bytes (192 nibbles), prefixed with 0x.

Condition

The aggregate_sigs handler should aggregate the signatures in the input, and the result should match the expected output.
