raster_info() already does this; it also converts the bounds and range
to numbers:

> grass.raster_info('elevation.dem')
{'north': 4928000.0,
 'timestamp': '"none"',
 'min': 1066.0,
 'datatype': 'CELL',
 'max': 1840.0,
 'ewres': 30.0,
 'vertical_datum': '(none)',
 'west': 590010.0,
 'units': '(none)',
 'title': 'DEM (7.5 minute) (elevation)',
 'east': 609000.0,
 'nsres': 30.0,
 'south': 4914020.0}
