[Enhancement] Add Start/End Date Filters To SecCompanyFilingsFetcher

[deeleeramone]

1. Why?:

   • While working on some other code that relies on this query, it became very evident this parameter should exist.

2. What?:

   • Adds the ability to filter start/end dates.
   • Adds the ability to filter by multiple form types.

3. Impact:

   • Enhanced outputs with targeted specificity to improve downstream operations relying on this function.
   • All filtering is done post-request, so there is no performance improvement collecting the forms.

4. Testing Done:

   • Updated integration tests with the new SEC parameters.
   • With/without start/end dates.
   • Multiple form types.

Warnings are collected if multiple form types are provided, but not all are valid.
