BambuStudio SoftFever V1.4.5
Changes:

Precise wall(experimental): improve model accuracy and layer consistency by fine-tuning the spacing between the outer and inner walls. I will explain more about how this works in WIKI in the future.

Added more built-in calibration tools; please refer to [WIKI](https://github.com/SoftFever/BambuStudio-SoftFever/wiki/Calibration) for more details:
    Temperature tower(model is a remix of [Smart compact temperature calibration tower](https://www.thingiverse.com/thing:2729076/files) )

    Max flowrate/volumetric speed test(model is a remix of [CNC Kitchen's Extrusion Test Structure ](https://www.printables.com/model/342075-extrusion-test-structure))
    max_volumetric_flow_preview
    VFA test(more optimizations for this will come in future releases)

Overhang performance improvements:
    Port PrusaSlicer 2.6's slowdown algorithm which works for both classic and Arachne engine. Kudos to https://github.com/prusa3d
    slowdown
    Implemented overhang fan speed for the new slowdown algo
    A new option to switch between classic/new overhang slowdown implementation

Bridge improvements:
    Added a new feature that allows changing bridge infill density. Sparse bridges are more appealing to our eyes in some cases:)
    bridge_density (1)
    Added a new setting to adjust acceleration for bridges

Set Arachne as the default engine

Change default top_surface_pattern to monotonic

Filter out tiny gaps option now applies to bottom/top layers

Improve small perimeter detection: overhang/bridge settings have higher priority than small perimeter settings.

Small perimeters are off by default now

Fixed a z-hop bug (https://github.com/SoftFever/BambuStudio-SoftFever/pull/279)

New printer: SP-5 Klipper @behold81

Improve gcode instruction generation for jerk

Update German translation for new calibration tools @hliebscher

cherry-picked some fixes from upstream
    Fix vase mode crash issue
    FIX: crush when slicer multi-color model
    the root cause is a mismatch between the dimensions of flush matrix and the number of extruders
    FIX: fix crash when switch printer
    ENH:close the amsmapping dialog when exit seletmachine dialog
    ENH:no longer hide the unload button when connected to AMS
    FIX: fix the slicing result different issue
    when move volume in objects copied from other object the result is not correct
    FIX: support blocker not work on vertical+horizontal faces
    FIX:fixed send print will crash when resources path is chinese path
