ZMK Config for Boardsource 4x12 Ortho

This project is a config for a custom ZMK Shield supporting the Boardsource 4x12 Ortho and 4x12 Ortho (LP) keyboards. The shield overlay and configuration files were based on the existing shield for the 5x12 Ortho. The keymap was modeled after the Planck and Planck EZ layouts with some customizations.
