Kangaroo test button is difficult to press when the Serial1 UART headers are installed

[dajtxx]

The button is sandwiched between the Feather headers and the UART headers and very difficult to press, would be good to have it moved to the opposite side of the board, in the corner near the 2nd SDI-12 header.

Basically, somewhere there isn't a lot of components sitting high above the board surface.
