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.

Create static drivers directly from source files.
...
Up to now static drivers were created via co65 from dynamic drivers. However there was an issue with that approach:
The dynamic drivers are "o65 simple files" which obligates that they start with the 'code' segment. However dynamic drivers need to start with the module header - which is written to. For dynamic drivers this isn't more than a conceptual issue because they are always contain a 'data' segment and may therefore only be loaded into writable memory.
However when dynamic drivers are converted to static drivers using co65 then that issue becomes a real problem as then the 'code' segment may end up in non-writable memory - and thus writing to the module header fails.
Instead of changing the way dynamic drivers work I opted to rather make static driver creation totally independent from dynamic drivers. This allows to place the module header in the 'data' segment (see 'module.mac').
