TurboJPEG: Expose/extend hidden "max pixels" param

Browse Source 
TJPARAM_MAXPIXELS was previously hidden and used only for fuzz testing,
but it is potentially useful for calling applications as well,
particularly if they want to guard against excessive memory consumption
by the tj3LoadImage*() functions.  The parameter has also been extended
to decompression and lossless transformation functions/methods, mainly
as a convenience.  (It was already possible for calling applications to
impose their own JPEG image size limits by reading the JPEG header prior
to decompressing or transforming the image.)

`TJ.PARAM_MAXPIXELS` in the TurboJPEG Java API) and a corresponding TJBench
option (`-maxpixels`) for specifying the maximum number of pixels that the
decompression, lossless transformation, and packed-pixel image loading
functions/methods will process.
