Feature suggestion: adding TIFFTAG_DATETIME to .tif outputs

[stephenwinn16]

Hi,

I'm looking into adding some metadata to the .tif outputs of ODM such that I have access to this information in a self-contained manner. Specifically, I would like the file metadata to include some estimate of the capture time (e.g. the mean of capture start/capture end times). I see here that geotiff files support the TIFFTAG_DATETIME tag (I use this info to e.g. get the capture time of satellite data I'm working with). Do you think it would be a case of adding an -mo argument to the GeoTIFF creation stage e.g. as is done below for the -co arguments?

ODM/stages/odm_orthophoto.py

Line 102 in e6e4095

kwargs['vars'] = ' '.join(['-co %s=%s' % (k, orthophoto_vars[k]) for k in orthophoto_vars])

As well as something similar for the DSM/DTM creation steps if they happen. I'm happy to take a shot at adding this to the source code if I'm on the right track here.

I think that could be useful and a pull request would be most welcome.
