Unminified version of navigation mixin

[mholthausen]

Hi @3DGISKing, thanks for providing your work to Cesium.

I tried to load the navigation mixin (https://github.com/3DGISKing/CesiumJsSamples/blob/master/Mixins/NavigationMixin/viewerCesiumNavigationMixin.min.js) into my Cesium project which is a webpack/node/typescript project. I'm not able to register the mixin as described in your example because I don't import "Cesium" but only specific components of cesium. Is it possible, to get an unminified version of that navigation mixin so I can try to include it and possibly remove unneeded parts?
Thanks for getting back to this.
