* Addede a bunch of abstract hdris as well as the option to cycle cle though them at runtime
* Added an extended PMREMGenerator that allows for the rotation of the hdri image.Now our IBL sources are finally straight not tilded 90 deg anymore. Added artificial shininess to all objects configurable in real time from the sandbox.
* Added color grading operations to our standard shader and material. Updated the sandbox to reflect the required AEC Aesthetics properties
* Restored the sandbox parameters to their original locations. Saturation, contrast and shininess are now in the 'post' folder and the hdri dropdown in the 'indirect light' folder. Cleaned up and renamed the available hdris to their descriptive names. The 'Mild' hdri is not set as the default one at library level
* Disabled color grading from the speckle standard material shader. Implemented the artificial shininess as a real thing that the user can control
