prog8/codeCore/src/prog8/code/target/encodings/PetsciiEncoding.kt
Irmen de Jong ddb8346711 added txt.cls() as a shorter alternative to clear_screen(). 
cx16: added new character encodings, and routines in textio to enable the character sets for them.
cx16: added txt.chrout_lit() and txt.print_lit() to always print the literal characters and never as control codes
