Add support for LyCORIS

[Hypi122]

Adds support for LyCORIS from https://github.com/KohakuBlueleaf/a1111-sd-webui-lycoris

I just mostly copied code for adding LoRA, so there could be some unwanted remnants from that.

When typing <l: it show both LoRA and LyCORIS

When typing <lora: it only shows LoRA

When typing <lyco: it only shows LyCORIS

Thanks, was just thinking about implementing this too this weekend. I had a quick look and wouldn't have done it any different.
