Added a second OSI C1P program file format.
...
Unlike the first format, the new format is already loadable; it doesn't need to be converted.

Match screen dimensions as in BASIC.
...
Experiments show that under BASIC by default
25 rows by 24 columns are used. 24 columns is
also the width that is fully displayed on a real
C1P on the monitor. conio now matches that now.

Implemented a one-character buffer for kbhit() and cgetc().
...
If kbhit() detects that a key is pressed, it fetches and
buffers the character. If cgetc() detects a buffered character,
this one is returned instead of fetching one with the PROM
routine.
