Is your feature request related to a problem? Please describe.

DM Mono is a 3 weight, 3 style family designed for DeepMind. DM Mono was loosely based off of DM Sans, with a reduction in contrast and less geometric proportions. I think it makes codes and scripts looking great and would make a great addition to Nerd Fonts.

Describe the solution you'd like

Distribute this font with necessary patches.
