Sony ILCE-6700 has invalid pixels on the right border

[che0]

Currently, ARW files from Sony ILCE-6700 map to 6264x4160 image, which has rightmost 26 pixels without any meaningful data. The effect is visible on this converted photo (Flickr link), as well as on compressed raw sample from raw.pixls.us when processed by RawTherapee 5.10.

The following camconst.json fragment fixed it for me:

    { // Quality C
        "make_model": "Sony ILCE-6700",
        "raw_crop": [ 20, 12, 6200, 4136 ] // columns after 6238 are b0rked; this crops the rest so that resulting image is 6192x4128, i.e. the same as camera JPEG
    },

Created PR #7076 with also the dcraw matrix. The raw crop used in that PR is the one provided by also other tools and looks saner.
