v2.0.0

From version v2 and onwards only c++17 is supported.

This version is a major refactor.

Fixes

• RotatingFileHandler will now correctly rotate the files when append mode is used (#123)

Improvements

• Reduced and simplified codebase.
• Improved backend worker thread performance.
• QUILL_DUAL_QUEUE_MODE has been removed. A single queue now handles every case.
• QUILL_STRING has been removed. That macro is no longer required when passing a format string to the
  PatternFormatter.

Differences

• v1.7 compiles with c++14, v2 only compiles for c++17.
• v1.7 on Windows supports wide character logging, v2 has limited wide character support such as logging wchar_t, std::wstring, std::wstring_view. For example, logging std::vector<std::wstring> is not supported.
• v1.7 on Windows requires the filepath used for the handlers as a wide strings, v2 supports only filenames as narrow strings.
