Virtual Filesystem (#597)
* Add VfsFile and VfsDirectory classes * Finish abstract Vfs classes * Implement RealVfsFile (computer fs backend) * Finish RealVfsFile and RealVfsDirectory * Finished OffsetVfsFile * More changes * Fix import paths * Major refactor * Remove double const * Use experimental/filesystem or filesystem depending on compiler * Port partition_filesystem * More changes * More Overhaul * FSP_SRV fixes * Fixes and testing * Try to get filesystem to compile * Filesystem on linux * Remove std::filesystem and document/test * Compile fixes * Missing include * Bug fixes * Fixes * Rename v_file and v_dir * clang-format fix * Rename NGLOG_* to LOG_* * Most review changes * Fix TODO * Guess 'main' to be Directory by filename
