chore(deps): Update @sindarius/gcodeviewer (mainsail-crew#1755)

Update @sindarius/gcodeviewer to latest after fix in upstream library.

First update (d34aa64) was to include OrcaSlicer in the supported slicers list;
unfortunately it was including a bug where unlisted slicer features where aborting the rendering.

The new fix in the upstream library ensures that if supported slicers will add new features
the render will continue to work and unsupported features will have a generic color instead of
abort the render and throw an error.
