Save stimuli / responses from the y[n] tab in HDL formats

[chipmuenk]

Useful formats would be:

• [ ] VHDL text file
• [ ] Verilog text file
• [ ] MIF (memory initialization file, Verilog)

For the export, the data format (float / int / uint / sfixed ... ) should be selectable

See e.g. https://www.javatpoint.com/verilog-file-operations or https://fpgacoding.com/test-bench-data-files-in-verilog/
