Add --exclude or --ignore in check-script-has-no-column-name

[laisdeghaide]

I have some dbt files that use generate_series to implement some useful CTE.
And I also have the check-script-has-no-column-name contract in my dbt-checkpoint that fails because of this CTE.
Would be nice to have an --exclude or --ignore to disconsider only some specific functions in the contract.

I know that check-script-has-no-column-name already has an --ignore for a file/directory, but this becomes unfeasible as I have several files with generate_series and I will disregard all other queries made in the same file
