[Dict] hotfix add hidden fields to dictionary implementation

[ridz1208]

Brief summary of changes

Some instruments use hidden fields which were not taken into consideration in this class. This should simply skip over the fields in the dictionary building

@driusan, @elPreeto STRONGLY approves my changes

This means that the hidden fields would never be in the data dictionary or queryable in the DQT. Is that the correct logic? What is the use case of "some instruments" using hidden fields?

[ridz1208]

@driusan the only couple usecases I have seen is to pass some data to the front end without it being shown to the user.

@CamilleBeau @laemtl @sruthymathew123 can you do a quick grep for hidden fields in your instruments?

We don't have any instrument fields hidden in that way.

@ridz1208 On HBCD, we don't have any instruments with hidden fields. @nicolasbrossard Can you check if anything exists on IBIS?
