Model Usage Table in README

[colt3k]

Problem

With so many models now offered it would be helpful to have a table on the README that lists them and which to use i.e.
NAME. RAM. PURPOSE
Optimized-Quality > 32GB Coding
Optimized-Speed < 32GB XXX
Optimized-Speedv2 > 32GB XXX

Proposal

NAME. RAM. PURPOSE
Optimized-Quality > 32GB Coding
Optimized-Speed < 32GB XXX
Optimized-Speedv2 > 32GB XXX
