Run ava tests on .ts files directly

* Before we had to transpile the tests first while has some draw backs.
* Failed tests now link directly to the .ts file
   - Can now control+click from the terminal to go to source
* Tests can now be run from the VSCode.
   - Using an extension such as testify.
* Running a single test file is about the same speed but it is 2x to 4x
slower when running the full test suite.
   - There is a lot of extra delay when starting the next test file.
* Followed this guide to add this.
