null characters from Avid AAFs

[thecargocultnz]

Avid Media Composer AAFs are causing JSON strings with null characters (\u0000). This makes it tricky to parse for anyone downstream.
Is there some way to sanitise these while parsing?

For the record: this example was caused by using the "Time Compression Expansion" Audiosuite effect.

Specifically, if you read the provided AAF, you get this in the metadata:
"AvidASPIPlugInName": "Time Compression Expansion\u0000\u0000\uf37e\u1029"

This appears to be a bug in pyaaf2. @thecargocultnz would you like me to submit this bug to the upstream project?

[thecargocultnz]

@jminor for ourselves we found a way to sanitise the data - but I'd say this would be worth fixing as it'll catch out a lot of people. So not urgent for us, but definitely a bug.

I filed a pyaaf2 bug here: markreidvfx/pyaaf2#49

[jminor]

This is fixed in pyaaf2 now: markreidvfx/pyaaf2@37de8c1

Next time there's a release of pyaaf2 we can update our dependency, but in the meantime you can pull the latest master of pyaaf2 to get this fix.
