Implemented typer for the Oric, and I'm starting to think the code is a bit too repetitious. Refactoring will be forthcoming. Added CLOAD"" as the loading command for all Oric software.

This appears to be it. The secret? Don't worry about the stop bits. They're just processing time. Latch onto the next start.
