v1.1.0 - Subworkflow modifier nodes

Added in this v1.1.0 release:

Modifier Nodes

If you want to expose an output from the inner workflow, modify it (for example, add loras to a model), and then pass it back into the inner workflow, you can use the Subworkflow Modifier node in combination with Subworkflow Modifier Source nodes.
The modifier node takes an input value, passes it through to its output, and also makes it available as a source for modifier sources. The modifier sources can be used in the inner workflow to access the modified value without creating circular reference problems.
