remove apply_qc_checks and other fns with qc_check_ prefix (#57)

with the new filter_qc function and the self.qc attrs (upcoming, see #56),
these unused functions are removed. #56 also explains how the whole procedure provides
more flexibility for the user in terms of QC selection of checks and filtering flags.
