BambuStudio SoftFever V1.4.2

Change notes:

1. Change the color theme :)
2. Fixed a crash issue when selecting vase mode on some machines
3. Port firmware retraction and Extra length on restart retraction feature from PrusaSlicer
4. Fine-tune calibration features
   • Enforce max volumetric speed in PA line mode
   • Ensure print speeds are consistent across all blocks in the flow-rate calibration process. This is to help users calibrate those challenging filaments(such as TPU) by minimizing the influence of printing speed - thanks @psiberfunk for his input on this
5. New printer models: thanks @erebus04
   • Tronxy X5SA 400
   • Artillery Sidewinder
6. QoL:
   • Now allow exporting g-code for BBL printers
   • Fixed a bug that printer connection info was removed after loading a 3mf project
   • fixed an issue that user presets were not loaded when Auto sync user preset option was off in Preference.
   • Germany language translation - thanks @hliebscher
   • README update and clean up - thanks @GP3D84
7. Misc fixes:
   • Exit calibration mode when a new model is added to the scene(creating a new project after calibration is recommended)
   • Skip emitting M106 P2 command if the auxiliary fan is not enabled.
   • Fix an issue that previously there was a z-fighting issue when bed models are used for 3rd party printers
   • Fixed an issue that max volumetric speed was not correctly calculated if flow-rate was changed per object.
   • CICD for Linux build - thanks @fang64

Known issues:

1. The Calibration menu is missing on some Mac machines. Try restarting the App can usually fix it. See #120
