jpeg2000.datatype 53.2 (22.12.2017)

- Made the code store the library base in cl_UserData again. Apparently this
  is needed for DisposeDTObject() to be able to close the library.

- Implemented write support.

- Added alpha channel support.

jpeg2000.datatype 53.1 (21.12.2017)

- Rewritten and updated to use openjpeg 2.3.0 (statically linked).

- Compiled with gcc 6.1.0.
