Didn't like that phi
Started on arbitrary resampler
Staring filter. Need to commit
Very basic arbitrary sampling is working.

Need:
    * Streamification
    * Tests
Simplifying arbitrary resampler
Added naive resamplers
Offloading arbitray resampler state calculations to another function
Temporary test code for new arbitrary resampler
Cleaned up test code
Restructured naive arbitraty rate resampler
Cleaned up temporary test
Fixed arbitrary rate resampler. It wasn't correctly indexing upper 𝜙
Arbitrary resampler seems to be working completely, but most likely is not. More tests needed.

It is way to complicated. Needs to be trimmed down. Also need to test if it is accurate enough to use accumulate a float 64 over time (assuming it is truncated to 1), instead of doing multiplications and divisions every time the filter kernel needs to be updated.
Added new naive filter routines to use as references, benchmark comparisons
Moved arb test code to runtests
Added arb testing code
De-typed naive resampler implementations
Got rid of unused debug print statements
