Phase offet (working, drawn) and Improved DX7 import

Phase offset working, is now drawn on the Osc osscilloscope view as a line and point of intersection (tested)
Phase is reset on note on, if not in slide mode with overlapping notes.
The phase offset allows for waveshaping, when frequency is set to 0! Use it on the Osc/Operator which is being modulated.
Import has been improved for DX7 patches using also the Modulation Matrix.

• Phase offset parameter on 1st Oscillator page
• Update build script to refresh release artifacts automatically after a successful build
• Add script options to configure release output paths and artifact names
• Regenerate release checksums and rebuild release zip from the script workflow
• Import DX7 oscillator phase behavior using key-sync approximation
• Set all operator phases to 0 degrees on import when DX7 key sync is ON
• Preserve existing operator phase settings on import when DX7 key sync is OFF
