Quantum noise sub-budgets

Kevin Kuns requested to merge kevin.kuns/pygwinc:quant-sub-nb into master
  1. Adds quantum noise sub-budgets. This addresses 1/3 of #51 (closed). Quantum noise can now be broken up into
  • AS port vacuum
  • Arm loss
  • SEC loss
  • Filter cavity loss
  • Injection loss
  • Readout loss
  • Quantum quadrature phase noise
  1. Changes the quadrature phase noise calculation as described in the comments below. This should close #20 (closed).
  2. Removes support for negative RMS phase fluctuations.
  3. Removes call to shotrad4 in some cases since this function no longer exists.

The sub-budgets are only implemented for the Cosmic Explorer interferometers since these are the only ones that have any other sub-budgets. Adding sub-budgets to the other interferometers is easy. The CE2 quantum budget is shown below as an example. quantum_vacuum
