Don't ask for consistency proofs based on an empty tree
...
RFC 6962 doesn't define how to generate a consistency proof in this case,
and it doesn't matter anyways since the tree is empty. The DigiCert logs
return a 400 error if we ask for such a proof.

Retrieve log list from certspotter.org at startup instead of embedding in source
...
The list of logs changes far too frequently (with annual shards and operators
dropping out of the ecosystem) to continue embedding in the source code.
Breaking change: the -logs option now expects a
JSON file in the v2 log list format, as documented at
<https://www.certificate-transparency.org/known-logs > and
<https://www.gstatic.com/ct/log_list/v2/log_list_schema.json >.
You can now specify an HTTPS URL to -logs in addition to a file path.
Breaking change: the -underwater option has been removed; if you want
this behavior then specify https://loglist.certspotter.org/underwater.json
as your log list.

Continue processing a log even if an STH failed to verify
...
It may still be possible to audit other STHs, and to scan new entries
up to the latest verified STH. This allows Cert Spotter to continue
to make forward progress even if a log is persistently skewed (as the
DigiCert has been lately).
Also, rework some code to be simpler and less redundant.

Save consistency proof along with evidence of misbehavior

Although the consistency proof is neither necessary nor sufficient
to prove misbehavior by a log, this will help with debugging if a
log returns a bogus consistency proof erroneously (which seems to
be happening with the Rocketeer log lately...).

Overhaul to be more robust and simpler
...
All certificates are now parsed with a special, extremely
lax parser that extracts only the DNS names. Only if the
DNS names match the domains we're interested in will we attempt
to parse the cert with the real X509 parser. This ensures that
we won't miss a very badly encoded certificate that has been
issued for a monitored domain.
As of the time of commit, the lax parser is able to process every
logged certificate in the known logs.
