Export Hair Particles with properties as alembic for Unreal Engine

Export of alembic groom for unreal engine is very limited because a lot of properties are missing.

• groom_id
• groom_color
• groom_group_id
• groom_root_uv

These would make painted hair in blender be imported to unreal Engine. At the moment there are some realy complicated and very limited workarounds to get painted hair from blender to Unreal Engine.

Please make it happen.
