digital: adds corr_est_cc correlation estimator block
This commit is almost entirely based on the correlate_and_sync_cc update
by Nick Foster <bistromath@gmail.com> and Andy Walls <andy@silverblocksystems.net>,
but has been renamed to corr_est_cc in order to be included in the 3.7 API
without compatibility issues.
