Update feeder types for Starknet 0.12.1

[joshklop]

Problem: Currently, we don't include the status in the feeder.Transaction struct. However, it is present in the response from the feeder gateway (example). This isn't a problem for us since we calculate the status on the fly in the rpc handler, but it could be a problem for developers who import the feeder package.

Solution: include all fields present in the feeder gateway response in the feeder.Transaction struct. We need to make the changes below.

With 0.12.1, the status enum is changing to include RECEIVED, REJECTED, REVERTED, ACCEPTED_ON_L2, ACCEPTED_ON_L1

Two more status enums are being added (related to #881):

• execution_status: REJECTED, REVERTED, SUCCEEDED
• finality_status: RECEIVED, ACCEPTED_ON_L2, ACCEPTED_ON_L1
