i.landsat.toar doesn't take into account the resolution difference between panchromatic and the other bands.

i.landsat.toar transforms the sensors DN to top of the atmosphere radiance/reflectance.
All bands except band 8 (panchromatic) have a pixel size of 30m. Band 8 has pixel size of 15.
When i.landsat.toar runs, it makes all the calculations with g.region res=30, which is obviously wrong for band 8.
I classify it as a a major problem , because band 8 carries double data and its being used in pansharpening techniques .
