[BugFix] Econ Calendar

[deeleeramone]

1. Why?:

Started as needing to add the list of countries to json_schema_extra in the TradingEconomics model, but ran into other items needing to be taken care of.

• Standard model contained parameters and data fields that were clearly only valid for TE, the description even named 'TradingEconomics'.
• Missing field definitions from TE response.
• Can't lookup by country, date, and importance.
• Literal choices not showing up in API docs.

2. What?:

   • Remove TE-only items from the standard model.
   • Add calendar_id as a parameter for TE.
   • Can now lookup by country, date, and importance.
   • Defined the missing fields in the TE model
   • Removed Optional from Literals and they now are proper choices in the API docs.
   • "Importance" parameter made lower-case.
   • Chunk dates for FMP so that start/end dates are not bound by a 3-month window.
   • TE group parameter had one choice with a space in it.

3. Impact:

   • @andrewkenreich, this renovates the models. Most notably, the choices for "importance" are now lower-case.
     • You will notice more fields, but I don't think you use them anyways.
   • New TE request parameter: calendar_id
   • TE country parameter now has: json_schema_extra={"choices": COUNTRIES}
   • TE requests can now do something like:

obb.economy.calendar(country="united_states", provider="tradingeconomics", start_date="2023-01-01", end_date="2023-12-31", importance="high")

4. Testing Done:

   • Unit and integration tests.
   • Check all providers.

Note that FMP does not have any query parameters other than start/end dates.

@deeleeramone this looks good. For some reason I can't get tradingeconomics to work inside the CLI. Is this the same for you @deeleeramone ?

So in the CLI I was getting:

2 validation errors for calendar
extra_params.importance
  Input should be 'low', 'medium' or 'high' 
    For further information visit https://errors.pydantic.dev/2.7/v/literal_error
extra_params.group
  Input should be 'interest_rate', 'inflation', 'bonds', 'consumer', 'gdp', 'government', 'housing', 'labour', 'markets', 'money', 'prices', 'trade' or 'business' 
    For further information visit https://errors.pydantic.dev/2.7/v/literal_error

Adding None to the Literal for each resolved that.

[IgorWounds]

Don't we want the Literal to be Optional? Sending a None through the API does not always work and can break.

@hjoaquim you already have some screenshots on this.
