feat: unescape escaped characters when value is not quoted

[bethesque]

Thank you for this handy gem. We use it regularly.

When using Ruby's shellwords library to escape values, the following env file is created.

export FOO=one\ two

Quotes cannot be used around those values, otherwise the backslash is considered a literal.

# incorrect
$ export FOO="one\ two"
$ echo $FOO
one\ two

# correct
$ export FOO=one\ two
$ echo $FOO
one two

This PR updates the code to correctly unescape characters when quotes are not used

The parse_value method had to be refactored to keep Rubocop happy.

This makes sense to me. @cadwallion, I'd love to hear your thoughts

[cadwallion]

Apologies for the slow response, @bethesque, this looks great! Thank you for the bump @bkeepers.

[bethesque]

Much appreciated!

Is there an expected date for the next release?

[cadwallion]

My plan is to review outstanding PRs/issues tomorrow and cut a release before the end of the day in the pacific timezone.

Hi. I know it's been a while, but as far as I can tell, this was never released. We're currently pointing our gem source at a private repo for this feature, but would like to change that to use the public gem. Could this be released please?

[bkeepers]

2.8.0 is out with this change. Sorry for the delayed release. Enjoy!

[bethesque]

Better late than never! 😆 Thanks!
