Stop LNK4221 link warning with link=static.
Fixed MSVC static analyser warning about writing off the end of an array.
Could find no code anywhere in Boost which uses to_time(), to_timespec_duration(), to_duration() nor to_microduration(), so removed the code.
Looks like timeconv.inl may be completely unnecessary, so remove.
Updated CI dashboard with latest tests.
Merge pull request #37 from ned14/develop
