feat: allow LoRAs with negative multiplier (#83)

* Allow Loras with negative weight, too. There are a couple of loras, which serve to adjust certain concepts in both positive and negative directions (like exposure, detail level etc). The current code rejects them if loaded with a negative weight, but I suggest that this check can simply be dropped. * ignore lora in the case of multiplier == 0.f --------- Co-authored-by: Urs Ganse <[email protected]> Co-authored-by: leejet <[email protected]>
