New features

Zoom buttons for spline (https://twitter.com/ossia_io/status/1317149631621570560) & nodal view
Filter-like processes will now directly pop-up in a small nodal patch which makes more sense (https://twitter.com/ossia_io/status/1317151628512854016)
-> as such, the effect / synth chains have been removed as they became quite redundant
macOS version is now codesigned and notarized. Please tell us if you have any trouble running the latest release.
When snapping to other scenario elements, a vertical dashed line will now be shown to make it evident that there is some snap occuring

Changes

In nodal view the ports are now laid out vertically which makes more sense and allows for cleaner layout
Faust synths now will only show relevant controls (not gain, freq, etc)

A lot were reported by @jln- ; thanks to him !

Fix that dropping a sound / video on a state did not create a new process afterwards
