Minor mistake in readme

[PLEXATIC]

The code example in the readme for using SegMoE with SDXL-Turbo appears to be slightly wrong. It imports the pipeline correctly, but then uses SegMoETurboPipeline out of nowhere. I tried to import that SegMoETurboPipeline and it wasn't found. Using the regular pipeline (SegMoEPipeline) in the import and the function call worked for me, hence my conclusion is that the docs must be wrong.

Thanks for pointing it out!
