[Feature Request] add the keybind to restart the typing test on click of "TAB" key

[wasup-yash]

Current:: There is no restart option (implicit or explicit) while the test is going on, if you want to start the new test then you have to either quit or finish the current test.

Feature:: Users can explicitly add the keybind to "TAB" in the config if they want to restart the test in between.

Note: already discussed on discord :)
