Spelling of NO2 TROPOMI variable

Hello, I noticed that in the file: mapies/tropomi.py

TROPOMI_PRODUCTS_DICT = {
    "NO2":"nitrogendioxide_troposheric_column",

there is a mistake in the spelling that should be corrected to:

TROPOMI_PRODUCTS_DICT = {
    "NO2":"nitrogendioxide_tropospheric_column",
