Move test runs into the test-run folder, add TimestampStrings, add basic tests via pytest

pytest added for dev.
Move all the test run python scripts into the "test-run" folder, so we can use the tests/ folder for just tests.

Setup one test for the TimestampStrings class with pytests in tests/unit/string_handling/test_timestamp_strings.py
