f382149086 Compensate initial buffering of anti-alias filter and intepolator. 
This avoids losing first few dozen of samples from beginning of the stream.

3d7bf376fd Tuning for ARM NEON 
Tuning to enable ARM NEON SIMD performance improvements:
- NEON detection in configure file
- Remove manual loop unrolling, gcc autovectorization does better job
without manually unrolled loops.
- Avoid unaligned pointer accesses when using NEON

fe15975a21 BPMDetect: Make conversion from size_t to int explicit 
Fixes warning C4267 on MSVC.

This assumes that `beats.size()` should never overflow `int` - if that
could happen, the API should likely be changed to handle it gracefully.
