Elemental Merge helper control

[wkpark]

This is a new Elemental Merge helper control (support SD + SDXL)

I'm not sure it is helpful, but It could be a bit easier than without this helper.

(blocks -> elements map will be auto-generated and cached.)

Haha i was just working on this exact feature when i stumbled on to this thread

Did Hako-mikan deny your PR?

[wkpark]

I didn't submit a PR because the control seemed too complicated. and above screenshot is the updated control (include "NOT" checkbox)

Looks good. I'm not sure if its possible to make elemental merging not complicated.
