    Add catch clauses for `WError` exceptions
    
    When using Exiv2 on Windows, some functions can throw `Exiv2::WError` and
    `Exiv2::Error` exceptions.
    
    + Added `Exiv2::WError` catch clauses to load/save file functions. Expect that
      wherever `std::wstring` is passed as parameter to Exiv2, has the potential
      to throw an `Exiv2::WError`
    + Added test file
    + Added regression test, checking `gexiv2_metadata_open_path()`
    
    Closes issue GNOME/gexiv2#66
