Regression tests for 0.41

[vbmacher]

Test whole emuStudio before release.

• z80-cpu, 8080-cpu: Frequency in settings
• Z80-cpu: default frequency 4 KHz
• z80-cpu, 8080-cpu: frequency spinner in status now reads real frequency

• ramc-ram: equal_count.ram:

• RASP, RAM, SSEM: implement Load image, dump memory and clear memory
• RASP memory: read .brasp files

[vbmacher]

• emuStudio application: reuse lexer on syntax highlighting
• emuStudio application: use better monospaced font (Fira Code)
• RASP-cpu: redesign status panel, add address debug column
• 88-sio: disable interrupts by default (due to CP/M 2.2)
• document better compiler examples

[vbmacher]

• Fix RAM/RASP serialization/deserialization

[vbmacher]

TODO: Support negative constants in RAM/RASP

[vbmacher]

• SSEM memory: GUI refactoring + fixes
• byte-mem: refactoring

[vbmacher]

TODO: SSEM-memory: cannot open binary file

[vbmacher]

• Brainduck: load source, emulate, stop, load source, compile, reset, emulate and:
