[Feature] - Use amplitude matrix for phases in command table

[GlaserN]

For measurements were the phase of the pulses is changed throughout the sweep, e.g., ramseys, the L1Q generates individual modulated waves, which are uploaded to the device. This may lead to an overflow in waveform memory on the SGs. The command table commands include the definition of the oscillator gain matrix, which could be directly used to implement the phase of the played waveform.

Describe the solution you'd like
The phase of the waveform should be encoded in the command table entry, instead of the waveform itself.

Describe alternatives or workarounds you have considered

Hi @GlaserN, thanks for reaching out.

We currently intentionally do not use the command table to encode the phase for general pulses, as there are some corner cases where this can lead to conflicts and potentially incorrect programs. (That is not to say our compiler can't be made any smarter in the future.)

Nevertheless, increment_oscillator_phase already does directly use the command table's phase offset register. I understand it is less convenient, but is that a feasible workaround at all?
