9246094033 Fix function pointer cast issues 
It is undefined behavior in C and C++ to cast a function pointer
to another type and call it that way. This does work in most native
platforms, however, despite it being UB, but in WASM it can fail.

See:

e129dfc27a fix TIFFReadScanline() call 
We were passing in 0 instead of -1, which could trigger an assert in
libtiff with some logluv images.

Also, fix logluv decode. We were not always resetting the decode format.
