Attributes listing and wheels usage

[petrvanekrobe]

This PR is merging the gdtf_attributes_with_description.json with the GDTF Attributes listing attributes_listing.xml Annex B (normative) Attribute Listing. This is to resolve #299 .

Further requirements:

• Update Channel Set - WheelSlotLink definition to refer to attributes needs for requirements of WheelSlotIndex usage
• Update all places with Emitter
• Update all places with Filter
• Update all places with Gammut
• Update all places with Wheel
• Update all places with WheelSlot
• Update all places with ColorSpace
• Update the attributes_listing.xml and set the required fields for each attribute, by default set to False now:

    "UseEmmiter": "False",
    "UseFilter": "False",
    "UseWheel": "False",
    "UseWheelSlot": "False",
    "UseGamut": "False",
    "UseColorSpace": "False",

Helper python script is still included, but can be removed later. Right now, it could be modified and re-run to change the default values / can also be done by find-replace...
