Support for a code-vs-data map in assembler and emulator

[floooh]

This would allow to automatically step over inline data after call instructions.

The assembler would need to add the information to the map file whether that line and address is code or data.

The emulator and emulator webapi would need to accept a new binary file format which for every address in the 16-bit address space has the information whether this address contains code or data.

The debugger 'heatmap' would be initialized with this information.

The step-over debugger feature would need to learn to step over inline data.
