sphear_fir_design: add tentative code to add an optional high frequency boost; create running averages for the A2B matrices and WXYZ filter shapes - both going up to the transition frequency and also down so that the transition between the two modes is smoother; plot signal power; make sure FIR size is correct, it was off by one

calibration: assume all impulse responses have been trimmed and windowed properly, do not try to determine impulse location; many changes in parameters and parameter order; do a running average of filter coefficients when designing the filter transition; determine the transition frequency automatically based on the maximum condition number of the A2B matrices

h2n: change triangular bridge to simple rounded rectangle, modularize most parts, many small changes in shapes - may not be a valid 2-manifold so we need to look at the fit of all parts so they fuse together

zapnspark: transform molex pin connector pads into smd pads to solder wires directly to the pcb instead of using connectors, should make it slightly easier to assemble the microphone; manually update the component location pdf and svg with new locations

zapnspark pcb: move and rotate R3, the end result is much better autorouting of traces and a bigger ground backplane (this change eliminates the weird routing around R1/R2 in the previous version)
