v0.3.0

0.3.0 - 2025-08-31

Various performance-related improvements.
~20% improvement in speed based on testing on an STM32H7 microcontroller.

Changed

• !Store filter coeffs and taps in opposite order (most-recent-last) to improve vectorization
• !Const-unroll compute intensive loops
  • !Limit size of FIR filters to <128 taps
  • !Limit order of polynomial fractional delay filters to <=10
• Add u value as initial for A*x dot product
  • (Potentially substantially) Improves float error for small values of latest measurement
    u at the expense of slightly worse float error for large u
• Update flop per eval count to 4N-1
• Update rust edition to 2024
