Subject: [PATCH] modernize against current scqubits

- environment.yml: bump scqubits 2.0 -> >=4.3 (the pin was years
  out of date); add ipyvuetify and qutip-qip, which the GUI and
  qutip demo notebooks need and which conda does not pull in
  transitively from scqubits.
- demo_customcircuit.ipynb: replace the deprecated
  scq.Circuit(zp_yaml, from_file=False, ...) call with
  scq.Circuit.from_yaml_string(zp_yaml, ...). from_file is
  deprecated as of scqubits 4.3.2. Source only; execution count
  and cached outputs unchanged.
