test-jig: minor silkscreen improvement

test-jig: add page notes to layout

test-jig: route led pcb

test-jig: small improvements to ground plane

test-jig: add pin descriptions to silkscreen

test-jig: properly position references on silkscreen

test-jig: all tracks routed

test-jig: reduce space needed for testpoints and solderjumper - use smaller solderjumpers footprints - 2 solderjumpers for I2C address selection instead of solderjumper + testpoint - smaller testpoint footprints

test-jig: pcb edges, initial placement of connectors
