In dinilu/EPDr: Interact with the European Pollen Database (EPD)

Description

This function removes taxa from the slot @commdf@counts in the epd.entity.df-class object based on specific groups of taxa. For example, the user can select to work only with pollen from trees and shrubs (TRSH) or with algae (ALGA). If x is an epd.entity-class object, this is first converted into a epd.entity.df-class with entity_to_matrices.
