RichardTea 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.

Ensures size_t cannot overflow
Limits the maximum contiguous memory allocation to something plausible.

Fix overflow in IOStreamBuffer 
`getNextLine` & `getNextDataLine` now double the buffer size each time
it is needed to avoid writing out of bounds.

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.

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.
