Adds a debug option for espanso when executing shell commands for greater context.

[deckarep]

In reference to the following: #355

I've added a debug flag for shell commands to utilize.

• When not provided debug defaults to false.
• When non-parseable debug defaults to false.
• When provided, error log is thrown which captures: cmd string, exit_status, stderr, stdout in a single log-line.
• I can attempt to add a relevant unit-test if this looks like a reasonable patch.

Hey,
Thank you for your contribution! I left you only a minor comment and then we are ready to go :)
Keep in mind that all changes are first merged into the dev branch and then, when releasing a new version, they get merged into master.

Cheers :)

Hey @deckarep,
I'm currently away and I'll get back home by Monday, I'll make sure to review the changes and merge it into dev next week.
Thanks again for your help :)

Sounds good @federico-terzi!

One question would you also be interested in PRs that provide optimizations both big and small? Some examples that come to mind I see are PRs where owned strings are allocated instead of using references. Of course bigger optimizations could be present in hot paths that might be more impactful.

@deckarep In general, I'd like to discuss all the PRs that get proposed as I really want to avoid wasting people time :)

I originally started espanso to learn Rust, so some of the early work was definitely not idiomatic. If I had the time, I would completely re-write it from scratch now that I have much better knowledge, but that would be mostly for aesthetics as espanso is already fast enough for most use-cases.

Merged, thanks for the help :)
