aaae3e3a10 size_t is 32bit on some platforms 
Also assert if size_t is smaller than uint32_t (probably not necessary)
Note: 32bit builds will crash OOM if a really large model is loaded, as cannot allocate that much in total, let alone contiguously.

932dfe0562 Fix overflowing allocations in MDLMaterialLoader 
Some allocations might underallocate due to integer overflows. This
commit ensures that we are throwing an exception if the allocation size
does not fit in an unsigned int.

30f17aa206 Fix heap out-of-bounds write in _m3d_safestr 
While there is a 256 character limit when computing the length of the
newly allocated strength, that limit was missing when copying the
string. This commit adds a new length check in the copy loop, preventing
it from writhing out of bounds.

656b0b25d8 Fix warning for array comparison 
The code previously compared two float arrays with the != operator. This is deprecated in Visual Studio 2019 and results in a warning that leads to an error when compiling with warnings as errors. Small fix to make the build work.
