UartTerminal: This is so fucking retarded, stop it

why make a dogshit hex input which is a copy of byte input but looks
ugly and stores data as ascii rather than actual bytes and then make it
reliant on the other dogshit text input module even though theyre
completely different??? i cba to even fix this its depressing
