f471b5fa30 j2k: restructure bitstream decoding 
This is based on jpeg2000 but differs because of
problems with the design from jpeg2000 with currently
supported files

More files can be decoded after this commit, though they
show heavy artifacts

8bedbb82ce j2k/jpeg2000: split data pointer in int & float. 
This fixes a TODO item and unifies both decoders structures
It also fixes undefined behavior due to aliasing violations

I choose 2 fields instead of a union because mistakely using the
wrong type with a union will lead to hard to debug "wrong output"
while with 2 fields mistakely using the wrong type will crash
with a null pointer derefernce which is much easier to debug

83fd377c94 j2k/jpeg2000: merge float DWT and related code 
the float conditions are largely changed to check the DWT
instead of the bitexact flag, which previously was wrong
(DWT53 is always int)
