tj3Set(): Allow TJPARAM_LOSSLESSPT vals from 0..15

The target data precision isn't known at the time that the calling
program sets TJPARAM_LOSSLESSPT, so tj3Set() needs to allow all possible
values (from 0 to 15.)  jpeg_enable_lossless(), which is called within
the body of tj3Compress*(), will throw an error if the point transform
value is greater than {data precision} - 1.

+3.0.5
+=====
+
+### Significant changes relative to 3.0.4:
+
+1. Fixed an issue in the TurboJPEG API whereby, when generating a
+12-bit-per-sample or 16-bit-per-sample lossless JPEG image, specifying a point
+transform value greater than 7 resulted in an error ("Parameter value out of
+range".)
