Handle GPS cameras
There are two cameras that have a built-in GPS for accurate timestamps, mostly for asteroid occultations. SharpCap and INDI are able to process those images to convert their metadata to FITS headers, but it's not the case of others and SER format. Metadata is provided in the first or last rows of pixels of each image, in binary form.
The two cameras are QHY174GPS (and possibly other QHY Pro series cameras) and DVTI+CAM.
