[PATCH] Visualisation of individual oxygen sensor data for CCR dives

I uploaded a zip containing 54 eccr dives obtained via dctool from a
JJ Petrel controller.


All dives use 0,7 and 1,2 as setpoints.

I hope they could be useful for testing this and future features. Just
keep them for future reference.

It's a shame I was not able to download all dives (108) from that
unit. He had a complete set of dives between sensor changes.
I always get a timeout error. I tried dozen of times without luck.
Host was a iMac. ATM I have no chance to find another computer.

On Petrel display I just get Bluetooth error: Send packet Err. (dc has
a new Saft battery).

Sometimes I got the error just few seconds after the start, sometimes
at the end of the Petrel countdown.
How does it work? Is it a watchdog or he pretends to complete the full
download within 3 minutes?
