[2024-practice-test]
Refactors the practice test to be incorporated with the test, removing any need for practice test mode.
Practice mode:
- Presents up to 20 screens to acquit the user with how the CogSpeed test works.
- These rounds are un-judged, and do not contribute to the remainder of the test.
- Roughly 4 correct answers in a row with an art less than right_count_art_less_than will continue on to self-paced mode. This is the only path to continue to self-paced mode.
- If more than 20 screens pass without the above-mentioned condition, the test will exit unsuccessfully with error code 4.
- Merges self-paced into practice-test
