Subject: [PATCH] fix(LamNI): stop double-printing the Xeye correction table

lamni_compute_additional_correction_xeye_mu() always printed its
result. write_alignment_scan_numbers() called it once per angle just
to grab the x-offset for the log file, which dumped all 12 corrections
up front -- immediately followed by the exact same values reprinted
one-by-one as tomo_alignment_scan() actually runs each angle. Add a
verbose flag (default True) and pass verbose=False from the lookahead
call.
