Allow for weighting options above 1 enhancement

[lundejd]

I have some textual inversions or Loras that need to be above a 1 before they really start to work. 1.5 is typical. If I enter those in the format:

{1.5::red|1.5::blue} for example, it appears to just treat red and blue as a value of 1.

When used with ControlNet it works well to push certain prompt values to a priority, or when you want a Lora to be able to overcome a strong Asian model set (examples).
