This change instroduces a mode where the Accelerate operation will be more aggressive. When enabled, it will allow acceleration at lower correlation levels, and possibly remove multiple pitch periods at once. The feature is enabled through NetEq::Config, and is off by default. This means that bit-exactness tests are currently not affected. A unit test was added for the Accelerate class, with and without fast mode enabled.
