[GRASS-dev] ASTER radiance, top-of-atmosphere reflectance and temperature

Hi all,

A couple of weeks ago I was having problems with i.aster.toar [1]. after
Nikos' input with his bash script for calculation radiance and reflectance
for ASTER images, I made a python version that calculates radiance,
reflectance (VNIR/SWIR) and temperature (TIR). Output of temperature can be
in Kelvin, Celsius or Fahrenheit.

The user can process all bands ('all'), pre-defined subsets (vnir, swir,
vnswir, tir) or a choice of bands.

Radiance is calculated by default, while reflectance and temperature are

I'd appreciate if anyone could test it.
