@kathryn-willi found that this function did not correctly read in a HydroVu HTML file where chlorophyll a is referenced as "Chl-a Fluorescence (RFU)" (file is "data/raw/sensor/log_download/2022/archery/HydroVu_Archery_-_TROLL_2022-03-31_01-10-25_Export-4.htm" for reference) should be as easy as adding an additional case_when line
