[Enhancement] Fixed Income Enhancements

[deeleeramone]

1. Why?:

   • SOFR belongs under the rate section with the other similar items.
   • Ambiguous standard model for EFFR and CP.
   • Moody's bond indices can be moved to be with the other bond indices.

2. What?:

   • Renames the "FED" standard model as: federal_funds_rate.
   • Renames the "CP" standard model as: commercial_paper.
     • multiple items allowed.
   • Add model definitions for all fields.
   • EFFR & SOFR: Standardizes the data from both FRED and the NY Fed API.
   • openbb-federal-reserve: Switch the source of the data to the NY Fed API and return a JSON.
   • openbb-fred: Add transform and frequency aggregation parameters. Return series metadata.
   • Moves SOFR to the fixedincome.rate router and add deprecation to the original item.
   • Add federal_reserve as provider to SOFR.
   • Return percentiles and notional volume for EFFR and SOFR.
   • Remove discontinued series from Ameribor and define the model with more information.
   • Add frequency and transform to Ameribor and allow multiple items. Renames "parameter" -> "maturity"
   • Adds overnight_bank_funding_rate as new route and data from FRED and Federal Reserve.
   • Adds "seasoned_corporate" as an "index" within the "us" category of bond_indices.
     • This returns the Moody's bond indices and the other endpoint can be retired - deprecation warning added.
   • Renames "hqm" files as "high_quality_market".
     • Changes the way data is fetched for "hqm" so that only 1 request per-date is made, and gets the 0.5-100 year range of yield curve for the spot rate.
     • Multiple dates allowed for 'hqm'.
   • Add Treasury Minus Fed Funds to Yield Curve as choice for FRED.
   • Renames "estr" -> "euro_short_term_rate"
     • Removes "parameter" paremeter and returns all items to a defined model.
   • Update associated tests.

3. Impact:

   • The only breaking change is the FRED parameter named, 'parameter'.
     • The same results are obtained by using the frequency or maturity parameters.
   • Additional data fields are returned from both providers to this endpoint.
     • Target ranges, percentiles, notional volume.
   • All fields returning a % value are normalized and have json_schema_extra definitions for front end.
   • Improved type hinting.
   • Much faster response time from obb.fixedincome.corporate.hqm

4. Testing Done:

   • Unit, Integration tests.
   • CLI
