Spec

1. Open the serialized key path
2. Read and parse the header (see the serialized key format)
3. Compute the offset of the body
4. Validate the header against the metadata provided by O(1) Labs in the verifier key filename
   1. header.kind.type
   2. header.kind.identifier
   3. header.constraint_system_hash
5. Load the key located at path, offset using bin_prot
6. Validate the header against the loaded key contents
   1. constraint_constants
   2. constraint_system_hash
7. Create the VerifierIndex structure containing the URS and key
