Why does `reflectance` accept multiple source images and `radiance` does not?

reflectance takes a list of sources as input: https://github.com/mapbox/rio-toa/blob/0a40beb1bd3c05c76c65f2f20951591d831ad5ea/rio_toa/reflectance.py#L131-L137

while radiance takes just one and expects that it contains multiple bands: https://github.com/mapbox/rio-toa/blob/0a40beb1bd3c05c76c65f2f20951591d831ad5ea/rio_toa/radiance.py#L64-L70

Why the difference? It should be easy to get the same behaviour in radiance with the principle used in reflectance: https://github.com/mapbox/rio-toa/blob/0a40beb1bd3c05c76c65f2f20951591d831ad5ea/rio_toa/reflectance.py#L93-L96

If there is no real reason for having two different interfaces, I suggest we harmonize them.

@j08lue thanks for the issue. I agree -- I don't think that there is any reason to not have them harmonized. Would you be able to submit a PR with the proposed change?

@dnomadb thanks for the response. I will make a PR.
