[Cin] libtiff 4.7.0 and libtheora 1.2.0?

[Andrea paz]

With Cin-appimage (tiff 4.6.0) it is worse, test.tif and
test_color.tif are not even displayed in the timeline (no problem with
file_example_TIFF_5MB.tiff): FVideoConvert::convert_picture_frame:
sws_getCachedContext() failed
Instead with the build with 4.7.0 the problems arise only in rendering.
I put the link to the 3 files, if you want to test; but I am convinced
that it is not a problem of CinGG or libtiff, but only of the 2
images.

Continuing to test, varying the names and bringing the extension from
tif to tiff, using one file instead of the 3 concatenated ones, etc.,
I always have different behaviors. Probably the cause is "me + the two
problematic images"!
