CRNLIB_ASSERT(num_threads <= cMaxThreads) fails on many-proc computers

[shinymerlyn]

I managed to "fix" this locally by bumping the cMaxThreads value in crn_threading_win32.h to 64.
Is it safe to bump this? Is it just for a sanity check, or are other things driven by it somehow?

Note: Could be this is a bug in an old version of the library. Haven't tried to repro on latest main branch here, since this is a very legacy project.

The offending line seems to be:
https://github.com/BinomialLLC/crunch/blob/master/crnlib/crn_image_utils.cpp#L605
It's not using the crn_get_max_helper_threads function when calling task_pool tp; tp.init(g_number_of_processors - 1);
