feat(door): Allow Shades to be assigned to Doors

We recently decided that it was weird that people could not assign shades to Doors but they could to all other geometry objects as noted by [this change in the schema](ladybug-tools/honeybee-schema#24).  This commit updates the measure to support this new feature and I also put the code that creates shade groups into a function so that we have less copy/pasted code.
