Enhance compartment schema specification for compartment data source groups

- Improve the ability for pycytominer-transform to handle groups of compartment data sources which may have different columns and/or datatypes by inference
- Do the same for column and datatype specification using a specific expected schema (instead of, for example, relying on the "first" file encountered by a procedure).
