Revamped Install Experience

This changes the installation script to use Miniconda3 inside the KoboldAI directory, this is MUCH more user friendly for the users.
Any existing python environment will be bypassed, and other dependencies like CUDA automatically installed with compatible versions.
With this approach we can better ensure that end users have the correct environment and won't run into other issues because of their existing installations, it also prevents the need for them to install anything else on their system as anything required is automatically downloaded.
