Logging

[garaytc]

Just idea that could be useful for debug

• auto versionning (last commit number?)
• verbose mode (env variable?) ; ==> could be useful to warn when not default behavior (like put item.title instead of opengraph.title in the embed)
• for unknown reason (?) open-graph-scraper didn't fetch URL it goes in the catch block ==> change error statement by a more details in the catch error (e.g. timeout / 403)
