Add option to print raw logs from search results.

[gibber9809]

Request

Right now the search script in the package will output logs in the format :raw_log when returning logs from clp-json.

Having a --raw-log option that removes the preceding colon and emits the logs as ndjson would make it easier to use the output from search without first having to parse it.

Possible implementation

1. Add a --raw-log option to the search script.
2. When emitting search results to stdout with the raw-log option enabled print them verbatim instead of prefixing them with :
