Allowed input file types for {episoap}?

[CarmenTamayo]

Currently the file type is .rds, which was updated from an .xlsx in the previous version of main (before merging #137)- I'd like to add to the explanatory chunk of code which file types are acceptable as an input for {episoap} but I'm not sure if there are others, e.g., .csv, that would also be adequate.

Since we use rio, all formats supported by rio are ok: https://gesistsa.github.io/rio/#supported-file-formats
