SANARubber a flexible version of SANA with i2i and multidiffusion/regional diffusion

### Model/Pipeline/Scheduler description

I made a pipeline that is as reliable as the basic SANA pipeline but more flexible by making it run an array of functions which runs everything the og pipeline does. this can make easy combinations if necessary.

here's the link, enjoy
https://github.com/alexblattner/SANARubber

example of multidiffusion in sana:
['bright moon','red','blue','green','black'] (first prompt is applied in the background
["0:0-512:512","512:0-1024:512","512:1024-1024:1024","0:512-512:1024"] those are the areas of the rest of the prompts
[.7,.7,.7,.7] those are the strengths of the areas applied with their prompts


again with i2i at stength .5 and the same settings as before (mild changes only):


ENJOY!
