Choose Head Size Based off of age of Participant

[audreymhoughton]

A short summary of what you would like to see in NiBabies.

Scale brain size flag based off of the age of the participant. Will need to find or make a table for the best brain size for each age.

Do you have any interest in helping implement the feature?

Yes, but I would need guidance

Add any additional information or context about the request here.

I think we should be able to help find / make a table. We should have a resource we can use through the BCP data. I don't have the bandwidth to help add into the code itself though.
