Report the municipality a missing CEP would have belonged toHEADv0.2.0main

A CEP that fails a lookup is rarely a random number: it is usually someone
who knows the city and guessed, and the classic guess is the -000 that 957
municipalities never received. The API now answers those 404s with a faixa
naming the municipality that owns the band the number fell into, which is
the difference between telling a user "invalid CEP" and "no such CEP in
Areal/RJ".

It is context for an error and never an address, so it rides on the
cepis_not_found condition instead of turning the failure into a success,
and cep_ini/cep_fim are the endpoints that exist rather than the range the
Correios publish - the interval between them is sparse, which is what ceps
counts. Parsing is deliberately unable to signal: a faixa that is null, an
array, a string or half a body leaves a clean not-found behind, because the
caller asked for the CEP, not for the decoration on its absence.
