o Parameterize the number of parity symbols
o Compute the residual lat/lon resolution after decoding
o Correct the initial lat/lon parts to match the assigned number of bits
o Reduce to uint32_t for en/decode of lat/lon, for Javascript target
o Test 1-5 parity symbols; confidence calcuation still seems incorrect
  for 1 parity, perhaps others.
