OS-9 Ghidra module

Ghidra extension to load and analyse Microware OS-9 for Motorola 68000 CPUs.

Ghidra version

This extension requires Ghidra 11.4 or a later version.

To use it on previous versions of ghidra, open ModuleHeader.java and replace every occurence of CommentType.EOL (introduced in 11.4) to CodeUnit.EOL_COMMENT, and import ghidra.program.model.listing.CodeUnit.
