Read .csv or .csv.gz

Would be nice if any time the recipe loads a `.csv.gz` (e.g. [loading load_data.csv's](https://github.com/cytomining/profiling-recipe/blob/51a3a4b36814c0a721a2062928a703ea46c169c4/profiles/profile.py#L438)) it instead checked to see if the file was there in either `.csv` or `.csv.gz` format and loaded whichever was present so that it doesn't crash if you miss compressing your input files.

Unless I'm missing some reason why this isn't a good idea?
