Adding keyBlock capability to support Programmmer's Dvorak

- Useful for partial redefinitions of keys
  Such as redefining Shift, which, as per the USB spec is handled by the OS
  This means we have to careful select which USB Codes to send to the OS to simulate Shift not being pressed (while it is)
- KLL capabilities only work with numerical arguments (KLL 0.3d)
- Each key must be explicitly block for each combination (e.g. LShift and RShift are handled separately)

- Adding example configuration for the Infinity 60%
- Adding example configuration for the Infinity Ergodox
- Requires kll.git 1a078b2b940709bc3c429c952d2f0d842927394f or higher
