Is your feature request related to a problem? Please describe.
My colleague needs MISR data cmorized. Refer to the documentation about this data here: https://asdc.larc.nasa.gov/project/MISR/MIL3MAEN_004

Would you be able to help out?
We already have a python cmorization script done internally but this needs to be expanded to more variables. After I have done this, I will create PR for this work.
