…more testpoints

4k7 might conflict with the max allowed current of some components on Glasgow.
It is a tradeoff against contact bounce when connecting the board, so do not increase
the value too much.

…autodetect

Powering off the jig & dut will prevent any glitches due to contact bounce and similar effects.

change all connectors to pogo pins to ones with 6 connections.
Will probably use some lever-type terminals like Wago 233 or Metz AST 041
for these. The 6 connection ones are easier to source for both types.

do not add the 3d model itself because of copyright reasons
it can be downloaded from Metz Connect (directly after registering) though

…ed layout

- use smaller solderjumpers footprints
- 2 solderjumpers for I2C address selection instead of solderjumper + testpoint
- smaller testpoint footprints
