pyqt5 on m1 mac

[elija-feigl]

Installing cadnano2.5 on one of the new M1 MacBooks is currently difficult due to its dependency on pyqt5.
pyqt5 is currently not providing an ARM compatible wheel (pyqt6 is) and has to be installed via rosetta (also using python installed via rosetta).

Posting this mainly as a resource for someone encountering this issue.
The m1 chips are still fairly new, a compatible pyqt5 version might become available in the near future.

For a potential workaround to install pyqt5 see f.i.:
