Ryan Malloy 86a5db5b08 Optimize pin mapping for direct bitwise GPIO ops ...

Rewire GPIO↔HMC472A so GPIO(n) = step bit (n-1):
  GPIO1→V6(0.5dB), GPIO2→V5(1dB), ... GPIO6→V1(16dB)

This enables single-instruction GPIO updates:
  GPIO.out_w1tc = (step & 0x3F) << 1
  GPIO.out_w1ts = (~step) & 0x7E

Replaces 28-line loop with 4-line bitwise code.
