Enhance info support such as outputing title

[iveney]

Info outputs a list of information. Definitely we can use awk etc. to extract the Title out, but it will be more convenient to have things like chrome-cli title or chrome-cli info.title to get specific information out.

IMO this is better: https://github.com/prasmussen/chrome-cli/issues/55 allows eg: chrome-cli --json info | jq -r .title
