Apply NormalizeIP to sidestream addresses during parsing

[stephen-soltesz]

This change fixes the triple-colon formatting in sidestream IPv6 addresses.

Around 2.7B rows in sidestream include ::: in the remote or local IP.

 web100_log_entry.connection_spec.remote_ip LIKE '%:::%' OR web100_log_entry.connection_spec.local_ip LIKE '%:::%'

This change uses a new function NormalizeIP that corrects this formatting. If the IP address is invalid for other reasons, it will be used as-is.
