/* This function is intended to be used for in-place swizzling, particularly after fread() of
- binary values from a file. Such as:
-
- numRead = fread(scale.mV, sizeof(float), 3, fp);
- llendianswizzle(scale.mV, sizeof(float), 3);
-
- It assumes that the values in the file are LITTLE endian, so it's a no-op on a little endian machine.
-
- It keys off of typesize to do the correct swizzle, so make sure that typesize is the size of the native type.

- 64-bit types are not yet handled.
