API spec is inconsistent with the the event status 'loading' #421
Description
The API specification says at in addEventListener section:
Note: The addEventListener callback shall be immediately called upon registration with the current TC data, even if the CMP status is loading and the CMP has incomplete TC Data, so that the calling script may have access to its registered listenerId. Furthermore, on every TC String change the callback shall be called unless it is removed via removeEventListener.
In the listing of the different CMP status it states:
-|-|-
'loading' | cmpStatus | DEPRECATED (this status is not distinct and will be removed in a future version)
-|-|-
Agreed that the 'loading' status may not be distinct. I don't know why we marked it DEPRECATED. So perhaps we change this description to so say: "Indicates the CMP is loading. (This status is not distinct and might be removed in a future version.)"
