do we want to add v4 telemetry?

Good catch. I've added a new enum and field for the market status. @mjk90 do you mind also taking a look at the EnhancedEAMercury proto and see if it makes sense?

Where would we set MarketStatus.Err?

The error is created by setMarketStatus and then returned by the ds.parse method.

what about marketstatus?

The zero value means CLOSED so it is a valid value. Unlike the price fields which are pointer valued *big.Int, the market status is a scalar uint32 so it can't be nil either.

* Add Mercury v4 * Uncomment out test * Add v4 telemetry * MERC-6004 Fix build * Update chainlink-common * Add changeset * Update market status proto enum values * Add changeset hashtag
Based off Mercury v3 schema with the addition of the market status field. The market status field is an enum which is represented as a uint32 here. This is the most compact width for both Protobuf and Ethereum ABI (uint8 is padded to 32 bytes).
Almost all of the changes are just pattern matching existing places where we fork on the schema version. The things to check for would be the integration test, the
datasource.Observemethod, and generally making sure that I haven't missed anything while copying.Note: this depends on corresponding changes in the
chainlink-commonand repo and smartcontractkit/chainlink-data-streams#73. I'll update this PR with the appropriate versions once those changes are in.
