backside v2.0

SD 1.5 Standard LORA

I improved the quality of data set and have a good result as expected;

I think the lora can meet our needs, so there may not need next version

because of low quality of data set, it can't use to generate high resolution image.

just use it to fine-tune the action in lower weight

maybe under 0.8

in the next version，I will find or create higher data set to train
