Created Old Bird redux detector v1.1 with improved filtering.

The detector bandpass filter length was fixed at 100 samples in version
1.0, which resulted in degraded filter performance at higher sample
rates. In version 1.1 the filter length is 100 for 22050 Hz input, but
varies proportionally for other input sample rates. More specifically,
the filter length is int(round(100 * fs / 22050)) for a sample rate of
fs Hz. This results in a much more consistent filter frequency response
at different sample rates.
