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: major reorganization of the code, factor blocks into several modules, make everything tilt according to the angle of the support columns, clean up all the major and minor junctures between pieces, almost everything seems to fall into place automatically

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)

changed all pads to be 1.99mm as there were problems with some components lifting the tracks when flexed - for example C2 and C4, hopefully this will fix this issue
