installers v2

This is a small release that has some batch files I created to make installing sd-scripts or kohya_ss easier to install. All you need to do is just put one of these in the folder you want to install everything in, and then right click -> run as admin. It'll do the rest.

new to this version:

• New guards to make sure that python 3.10 and git are installed
• less cluttered messages so that is makes more sense what is going on
• the option to install the cudnn patch for higher end 30X0 cards as well as 40X0 cards, using the installer script written by bmaltais. Thanks bmaltais
• the option to auto install the patch for 10X0 cards, for the sd-scripts installer only
