LilacSat-2 telemetry PDU decoder

Recently, I showed my experiences receiving and decoding LilacSat-2 telemetry. I managed to get 15 packets of 4k8 GFSK telemetry and 15 packets of 9k6 BPSK telemetry during a single pass. However, I couldn't decode these packets because I didn't know the telemetry format. It turns out that Mike DK3WN has released a decoder software. Here I show Mike's software decoding the packets I received.

The decodes for my telemetry packets are shown below. Incidentally, the second 9k6 packet I received is the same one as the first packet on Mike's post showing the telemetry decoder. This is handy, because I can check that I really get the same values as him (and you can see that in the image). A number of telemetry channels don't seem to be working properly and give invalid data. This seems normal, as the same happens to the data in the telemetry server.
