remove DI box

I don't really need a DI box all the time. It complicates the circuit,
draws more power, and requires more space.

An external DI box can be connected to the mono output for the same
result.
first complete layout draft
use this expensive voltage reference instead of a voltage divider
power supply filtering
adjust value and size of support caps
more biasing with reference voltage
rename power connector to make it appear on PCB
move power rails filtering to power supply
add jumper to connect Vcc nets
update board
