Subject: [PATCH] lal_complexfirbank: fix handling of high frequency gaps
-the code needs to know how many input samples are needed to drain enough of the history for there to be nothing but 0s remaining. to determine the amount of non-zero history, instead of counting contiguous non-zero samples from the start of the history count contiguous zero samples from the end and subtract from the total.
