ENH: Load bands as radiance #54

Open remi-braun opened 2 years ago

remi-braun commented 2 years ago

For now, we can load bands "as is" and converted to reflectance.

It would be great to allow the user to load bands as radiance too, as asked in #50.

It may be also pertinent to differentiate TOA and BOA reflectances.

The current workaround is:

loading the bands "as is"
then using the following private method (this isn't tested but should work):
```
# Convert DN into radiance
nir_array_rad = prod._dn_to_toa_rad(nir_array_dn, NIR)
```
⚠️ This methods doesn't exist for every optical products!
