Fix duct

[eytanadler]

Purpose

The compressible duct with the heat exchanger included (ImplicitCompressibleDuct rather than ImplicitCompressibleDuct_ExternalHX) did not have working connections. I think they were probably not updated after other components had been changed or added to the one with the external HX. I've changed them so they match the external heat exchanger one.

I also realized that the pyCycle tests are not run GitHub Actions because pyCycle is not installed. I added the latest version to the install and fixed an outdated pyCycle option in the tests.
