NAM file format version bump for A2?

[mikeoliphant]

The example A2 file here:

https://github.com/sdatkinson/NeuralAmpModelerCore/blob/main/example_models/wavenet_a2_max.nam

is still showing "0.5.4" as the file format version number.

I'm assuming this will get bumped when "real" A2 models roll out?
