AFT-726: disable b-tagging in some edge cases

This adds the ability to disable NNs when there are too few tracks associated to the jet. Right now it shouldn't do anything: I've set the minimum number to zero. We can set this to 1 to fix some of the issues we were seeing in AFT-726, but I'll wait until we've studied this more.

Quite a few steps are required:

• Allow custom default values
  • Specify these in the configuration
• Find a pattern to match to NNs that have this problem (disabled for now)
• Figure out what default values to decorate
• Port to 24.0
• Enable in the trigger "fast" flavor tagging configuration
  • Add an AND condition of some kind with the existing conditional decoration
