Fix insertion of GPSProcessingMethod tag

GPSProcessingMethod was not being inserted properly because it
was being treated as STRING format which results in "ASCII" being
taken as the processing method. GPSProcessingMethod is defined as
UNDEFINED format with the value containing a character string in
Exif2.2 standard.

1. Set GPSProcessingMethod to UNDEFINED format as defined in Exif2.2
2. Add handling of ASCII value with UNDEFINED format in writeExifTagAndData.
Handling is similar to STRING format, except we have to account for the
'ASCII\0\0\0' header before the string.
