stitching.merge_images doesnt have a dest_epsg argument

[scottstanie]

Right now we can specify bounds, as well as the EPSG code of the bounds' coordinate system. But we can't say "reproject all these images into EPSG:XXXX".

Lines 199 to 200 in d8fd3c8

	# Make sure all the files are in the same projection.
	projection = _get_mode_projection(file_list)

It always gets the most common projection of the inputs to use
Since this makes sense in a lot of cases, we should decide

• do we want to add a dest_epsg argument so we can always force an output projection?
• or should we just say "a user should to gdalwarp ... afterwards if they dont want the most common projection?
