Return all conditions codes via 1 API call, include aggregation rules.

Is your feature request related to a problem? Please describe.
Retrieving all Conditions Codes requires 6 API calls (trade/A, trade/B, trade/C, quote/A, quote/B, quote/C). It's not much data, and I assume it changes rarely or never. Seems like we should be able to get all conditions with a single API call.

Describe the solution you'd like
Return all Condition Codes for trades and quotes and all tapes via a single API call. It would be especially nice if the response included aggregation rules similar to the Polygon API.

Describe alternatives you've considered
Using Polygon's API.
