Feature description

implement support for lier lora network types

lora concepts sliders are based on two network variations: c3lier and lierla those two networks were first defined in leco lora: https://github.com/p1atdev/LECO/blob/main/lora.py

reference implemnentation for concepts sliders: https://github.com/rohitgandikota/sliders seems like actual network in https://github.com/rohitgandikota/sliders/blob/main/trainscripts/textsliders/lora.py is pretty much the same as leco original? (although not sure why is there separate https://github.com/rohitgandikota/sliders/blob/main/trainscripts/imagesliders/lora.py) and loader plus how to set scale is notebook: https://github.com/rohitgandikota/sliders/blob/main/SD1-sliders-inference.ipynb
