Add getters for GPS time data #31

Closed theduke closed 5 years ago

Hey, great crate!

An awesome addition would be getters for the GPS date/time fields that return chrono types.

sample values:

    GPSDateStamp: "2010:09:28"
    GPSDateTime: "2016:09:19 23:07:17Z"

Hi! Thanks for the suggestion! Do you know where those fields might usually be found? E.g. in XMP, IPTC, EXIF, or somewhere else? Under what name?

I ask because skimming the upstream gexiv2 docs I don't see GPS timestamps mentioned. To support this might mean first adding an accessor function upstream — unless there's a specific existing tag we can read from in a generic way?

Closing this for now since I'm not aware of anything upstream that would let us do this, but I'd be very happy to have this functionality if anyone were to find a mechanism for it! Thanks for the suggestion!
