[FR] Blind Control - Allow configuration of slat position additional to level

[Hypnos3]

Ermögliche es einen payload von "L=$1,L2=$2" mit (L1=Behanghöhe, L2=Lamellenwinkel --> "L=100;L2=50") zu setzen.

Idee:

• Den Output payload auch konfigurierbar wie die Topic mit Platzhaltern zu haben.
• Für die Rules einen zusätzlichen Parameter neben Level zu definieren (Slat), der eher wie die Topic behandelt wird.
