Daisy chain tests of second DDC232 prototype in D109

Aim: Debug "mirroring" issues when daisy-chaining more than 2 DDC232s boards.

Notes

DDC232 boards have a numerical identifier:
- Board 1: S1337-16BR photodiodes
- Board 2: 1k ohm resistors
- Board 3: S1227-16BQ photodiodes
- Board 4: S12915-16R photodiodes
In the runs listed, boards are listed right to left, with the right-most board connected to the FPGA.
In all runs, an integration time of 170us and full-scale range of 350pC is used.
