No warning when material modification is unused

Right now if you define an assembly with a material modification that is not recognized, ARMI does not tell you that it isn’t recognized or that it is unused. For instance, I can define an assembly:

assemblies:
  Testing123456:
    specifier: IC
    blocks:
    - name: DriverFuelBlock
      flags: FUEL
      fuel:
        shape: Circle
        material: UZr
        Tinput: 25.0
        Thot: 1500.0
        id: 0.0
        od: 0.5
        mult: 217
    height:
    - 666.0
    axial mesh points:
    - 666
    xs types:
    - B
    material modifications:
      this_is_a_fake_setting: # <--------------------------
        - 0.5

No mention of the modification this_is_a_fake_setting is made in the output. It would be useful for the user to know that their modifications are not recognized, at the very least as an input verification mechanism.

Is this a good first issue for someone without access to the GUI?

Yup! It looks to me like it is a bug in the code that reads blueprint files. If we can make some sort of log message happen when ingesting a blueprint with an extra config setting, that would be all we need. I might suggest to use a Warning-level log message.

And I don’t see any reason the work would involve the GUI. It should be completely unit-testable.
