* Begin CrOS implementation for Framework Laptops * CrOS: Talk directly to the EC, instead of through ACPI * Add a few Framework models * Remove early Framework models These have a different EC, and don't currently work * Migrate CrOS ECs to PawnIO * Implement EcCommand and read sensor names * Add more Framework models * Add some error handling * Misc --------- Co-authored-by: PhyxionNL <7643972+PhyxionNL@users.noreply.github.com>
