CMP_CompressOptions->m_PrintInfoStr is marshaled incorrectly

[ProbablePrime]

On linux, CMP_ConvertMipTexture fails whenever it tries to access m_printInfostr.

This is marshaled from us here: https://github.com/Yellow-Dog-Man/Compressonator.NET/blob/main/Compressonator.NET/Structs/CMP_CompressOptions.cs#L134

It appears we marshal it incorrectly.

To fix this one:

1. Adjust marshaling of m_printInfostr
2. Compile a new version of Compressonator Native and Remove/revert: Yellow-Dog-Man/compressonator@a23d2e4 which IFDefs out m_printinfostr.
3. Submit as a PR
4. ALL tests must pass on all operating systems
5. ideally add a new test showing successful functionality being handled with new marshaling.

It is also marshaled incorrect on windows.
