conductor: parse oracle data from extended_commit_info and send to rollup if it exists

[noot]

once the extended commit info is inside SequencerBlock and written to DA, conductor can access it and send the data inside of it to rollups.

conductor does not need to do additional validation on the extended commit info, as it will only be finalized by the sequencer if valid.

the RollupData enum should be updated to contain an OracleData variant, which can be a vec of prices such as:

message Price {
  CurrencyPair currency_pair = 1;
  QuotePrice price = 2;
  uint64 decimals = 3;
}

conductor then needs to parse the extended commit info into a OracleData by parsing the prices and taking the median (logic which is already implemented in sequencer) and then pass this as a RollupData to the rollup.
