Disconnecting mEDBG

The target controller ATtiny817 can be completely separated from the mEDBG, but this requires some small
modifications to the board using a soldering iron. By removing the resistors in the sections shown in the figure below,
the mEDBG is completely disconnected from the target controller. To reconnect the mEDBG again, solder in 0Ω
resistors or solder in 100-mil headers on the header footprints and use wire-straps to connect the interfaces.
