Build failure with Boost 1.85.0

[cho-m]

mupen64plus fails to build with Boost 1.85.0:

  In file included from ../../src/GlideHQ/TxFilterExport.cpp:28:
  In file included from ../../src/GlideHQ/TxFilter.h:29:
  ../../src/GlideHQ/TxHiResCache.h:50:48: error: no type named 'wpath' in namespace 'boost::filesystem'; did you mean 'path'?
    boolean loadHiResTextures(boost::filesystem::wpath dir_path, boolean replace);
                              ~~~~~~~~~~~~~~~~~~~^~~~~
                                                 path

According to https://www.boost.org/doc/libs/1_85_0/libs/filesystem/doc/deprecated.html, typedef basic_path<std::wstring, wpath_traits> wpath was removed.

It would be good to get a fix in while Boost is still a dependency. Alternatively, removing boost (#46) in a release would resolve this issue.
