feat(thumbnails): register Nikon NRW and Sony SRF raw previews
...
Both are TIFF-based camera raw formats handled by the same generic walker;
NRW detection needs the reva mimetype mapping in opencloud-eu/reva#773 , SRF is
already mapped. No sample files on hand for these two, added by format
structure alongside their verified siblings.

feat(thumbnails): serve raw previews for CR2, PEF, ARW, SR2 and DNG
...
Rename RawImageDecoder to RawTiffDecoder and qualify candidates by their
actual stream instead of trusting the tags: CR2 keeps its full-size JPEG
as an IFD0 strip, DNG stores the raw sensor payload as lossless JPEG
(SOF3) which starts with a regular SOI. A JPEG segment walk to the SOF
marker accepts only the DCT processes common decoders render.

Fix GeoGebra thumbnails when libvips support is enabled
...
For GeoGebra files we where still using the imaging package to decode the
embedded png, but handed it of to vips for scaling, which can't work. Now
we use vips for decoding the image as well.
