DB48X: HP48-like RPL implementation for DM42

[spiff72]

Quick questions about the latest version of the firmware for DB48x...

1. I must have missed a few updates because I was still on 0.7.13. I installed the new version today and got a warning message about this program not being targeted for this hardware. Is this normal/expected behavior? I pressed 1 to continue, and it still seems to run OK. I did install the included QSPI file first.
2. Is there anything special that needs to be done with the keymap file that is included in this release? I saw mention in the release notes about a keymap being included but I thought it was to solve an issue on the DM32 hardware.

Thanks!
