Gives the user a possibility to dynamically change the history size. The main advantage is, for example, that you now can start with a wide delay range and over time decrease the search window to lower complexity. Adds - two new APIs. - and updates unit tests. - a history_size member variable to BinaryDelayEstimator. - two help function re-allocating buffer memory. One thing that makes this a little complicated is that you are allowed to have multiple delay estimators with the same reference, so changing the buffer sizes at one place will automatically give you a mismatch at other places.
