Update EthQL to be EIP-1767 Compliant

[kshinn]

As the schema for EIP-1767 develops, we should review the Ethql base spec and ensure that it is compliant. It is expected that there will still exist overlay features to enhance the base spec. However EIP-1767 should be covered as a subset.

Acceptance criteria

• Type specificity (Defined types should align closer to the spec)
• Block without argument should default to LATEST. Other supported tags may still exist.
• eth_call nested within the block should be supported.
• logs as an attributed within Block
