Improve rule evaluation errors

[ligustah]

• implement Display, Serialize and Error for Results type
• wrap the Results in the returned error (so it can be inspected further up the stack)

Error is now looking like this:

WARN mintpool::controller: Invalid premint, not broadcasting: Premint failed validation

Caused by:
    Metadata::token_uri_length: Accept
    Metadata::existing_token_uri: Accept
    Metadata::signer_matches: Ignore (No existing premint)
    Metadata::version_is_higher: Ignore (No existing premint)
    PremintTypes::ZoraV2::is_authorized_to_create_premint: Accept
    PremintTypes::ZoraV2::is_valid_signature: Reject (Invalid signature for contract admin 0xD272a3cB66bea1fa7547DAD5B420D5ebE14222E5)
    PremintTypes::ZoraV2::is_chain_supported: Accept
    PremintTypes::ZoraV2::not_minted: Accept
    PremintTypes::ZoraV2::premint_version_supported: Accept

JSON looks like this:

    "result": "accept",
    "reason": null,
