`TypeError` when extracting GPS information

[stecrotti]

Trying to extract GPS information results in a TypeError.
I've tried a bunch of GPS-related tags and they all seem to be giving the same.

MWE:

using TestImages, ExifViewer
filepath = testimage("earth_apollo17.jpg", download_only=true)
io = open(filepath, "r")
read_tags(io; read_all=false, tags=["EXIF_TAG_GPS_LATITUDE_REF"])

gives

ERROR: TypeError: in typeassert, expected Vector{ExifViewer.LibExif.ExifTag}, got a value of type Vector{ExifViewer.LibExif.ExifTagGPS}

I think the issue might be that here a check is done that all of the read tags are of ExifTag type, but ExifViewer.LibExif.ExifTagGPS <: ExifViewer.LibExif.ExifTag evaluates to false.
