Dynamic notch filters on pitch axis are not limited by dynFiltNotchMaxHz

[Ladislawv]

Describe the bug

There is a problem with dynamic notch filter or in the code that packs data for blackbox logging.

Dynamic notch filters on pitch axis are not limited by dynFiltNotchMaxHz. They are up to 800hz most of the time. On the roll axis everything seems OK.

There's no difference between the latest dev build from yesterday and BF 4.2.5. Tried it on two different quads.

To Reproduce

Set debug mode to FFT_FREQ and check Center Freq [pitch] trace.

Expected behavior

Center freq for pitch axis dynamic filter should be limited by dynFiltNotchMaxHz.

This is simply a case of the debug element labels in the blackbox viewer not being updated to match the information actually written to the log in the firmware. At some point the logging changed int eh firmware and the blackbox viewer was not updated to reflect the new contents.

Moving to the blackbox viewer repo.
