opj_compress and opj_decompress entries in DocJ2KCodec Wiki page have garbled library requirements

[dnygren]

Under both the opj_compress & opj_decompress entries at the DocJ2KCodec OpenJPEG Wiki Page there is a portion that reads:

"For PNG resp. TIF it needs libpng resp. libtiff ."

This seems to be garbled. It probably should be written as:

For PNG, libpng is required. For TIF, libtiff is required.

or maybe

For PNG and TIF, libpng and libtiff are required respectively.
