Flexible 2d charge scan on current HDAWG firmware

[terrorfisch]

@Nomos11 do you still know what flexible is supposed to mean?

Which discussion was this issue based on?
I don't remember particular things that would necessitate an issue right now

Can we do a 100x100 csd in virtual gate space with the current driver?

probably only with the linspacebuilder and this branch: https://github.com/qutech/qupulse-hdawg/tree/linspace_builder
it's not merged to main because of lack of tests (I tested the examples from the linspacebuilder-tests though), explicit enforcement of some restrictions and documentation.
With the "standard" loop builder it may only be possible if using "to_single_wavefom" cleverly. (there exists another hacky private version, and one could do more with the loopbuilder, but it's probably not worth the effort considering this is what the linspacebuilder was conceived for)
