avcodec/tiff: Enforce increasing offsets
...
This may break some valid tiff files, it appears the specification does not require
the offsets to be increasing. They increase in the 2 test files i have though except
the last offset which is 0 (an end marker) and for which a special case is added to
avoid asking for a sample for that end marker.

for an alternative implementation
Fixes: Timeout (Infinite -> Finite)
