feat(dump history): You can specify the time range, regex and format to dump

[TD-Sky]

Implementation of #372.

Now you can dump the history. For example,

$ mcfly dump > history.json

will dump the whole history into json file.

Here are the options:

      --since <SINCE>    Select all commands ran since the point
      --before <BEFORE>  Select all commands ran before the point
  -s, --sort <ORDER>     Sort order [case ignored] [default: ASC] [possible values: ASC, DESC]
  -r, --regex <REGEX>    Require commands to match the pattern
  -f, --format <FORMAT>  The format to dump in [default: json] [possible values: json, csv]
  -h, --help             Print help

The timestamp (since/before) format is subject to chrono-systemd-time which is a non-strict implementation of systemd.time.

I think the PR isn't in the final stage now so suggestions are welcome.

Awesome, I'll test this out shortly. Thanks @TD-Sky

@TD-Sky would you be able to also update the mcfly help dump page and README with example usage and especially a timestamp example or format reference?

[TD-Sky]

Let me have a try.

[TD-Sky]

You could review README.md now.

Sorry for my delay, I'm busy these days.

Any plans to merge?

Any plans to merge?

chrono depreciated some APIs we are using. I may need to refactor chrono-systemd-time to adapt the correct APIs.

[TD-Sky]

Fixed.

[cantino]

Thank you @TD-Sky for this nice addition!
