* Previously we were not properly parsing the storage field of GenesisAlloc. The first issue was in using serde(flatten), which is just incorrect because storage is not encoded flattened. The second issue was in the parsing of H256 keys and values. Some of the storage values in hive genesis examples were encoded in less than 64 hex characters, such as the string `0x12`. This would not succeed normal H256 parsing. * Introduce from_unformatted_hex_map to properly deserialize the storage map. * Modify existing genesis parsing tests to check parsed storage and code values against expected values. * Introduce new genesis parsing test from the hive smoke tests, checking full struct equality.

Motivation
Previously we were not properly parsing the storage field of GenesisAlloc. The first issue was in using
serde(flatten), which is just incorrect because storage is not encoded flattened. The second issue was in the parsing ofH256keys and values. Some of the storage values in hive genesis examples were encoded in less than 64 hex characters, such as the string0x22. This would not succeed normal H256 parsing, but is consistent with JSON-RPC unformatted encoding.Solution
