Add measurement builder

[shumpohl]

First version of a measurement builder. It produces a sequence of wait, measure and loop commands that can easily be translated into arbitrary formats. There is a translation to the currently used (begin, length) table in ``to_table`.

Following thigs are to note:

• The commands support HardwareTime arguments which is not implemented by any measurement device afaik but could be.
• The commands allow negative delays to make time inversion easy. This makes consuming the commands harder because all previous measurement times could be needed.
• The table conversion with the python "VM" is rather slow

Remaining tasks:

• Doc strings in the code
• Make measurement window handling in the pulse templates more lenient.
  • Allow windows that leave the PT
  • Allow symbolic windows
• Add tests for repetitions
• Add tests for nested iterations
• Add tests for time reversal
• Example usage with MeasurementBuilder and to_table
• Add a normalization function that gets rid of negative delays

Nice to haves:

• Data analysis that uses the commands. Maybe it can be integrated in atssimple @maxbeer99 ?
• Speed up table translation with numba
