7846b0c469 convolve: Optimize and special-case floats 
Special casing floats decreases runtime to about 50% (applying a 117-tap
filter to 512 points of data goes from 70ms to 32ms)

The top_n/bot_n calculations already meant that the a/c indices were
never out of range.  This decreases runtime further to about 15% of
original (11ms)

Timings done on an Adafruit Clue (nrf52840 at 64MHz)

It does of course increase code size somewhat.
