v2020.3 values return optionals

Column values now return optional rather than T{} defaults. This allows values to differentiate between null values and empty string or actually integer values that are 0.

v2020.2

• Adds support for #30 Some automation tests!

v2020.1

1. New versioning schema, .
2. Added CI
3. Removed lift::Eventloop and libuv worker threads in favor of lift::Executor
   • Executors will spin up worker threads to execute queries synchronously.
   • API allows for a callback on completion (executed on worker thread)
   • API allows for a future to be returned to block on/check if completed.
4. Added pthread id + os thread_id for renaming/monitoring threads.
5. Added code coverage (not great yet but WIP)
6. Namespaced the example projects with "wing_" prefix to not nameclash with other projects.
7. Simplified the wing::GobalScopeInitiaizer{} so there is only one way to use it.
   • Played around with a std::atexit() for issuing the mysql_library_end(), it didn't appear to work correctly.
