Sort output by least difference

[ibLeDy]

When the user inputs multiple timezones, we could sort the output so after the local timezone there's always the one that has the least difference.

• We should try to preserve the user order, so if there's no difference we use the input order.

• We may also add an argument to preserve the user order even if the sorted output would be different. Maybe we can use--preserve-order or --no-sort? Or maybe even have this feature as an opt-in via --order

For example, in the following screenshot, new_york has less difference than tijuana, so the sorted output would be:

1. local
2. new_york
3. tijuana

@ibLeDy as part of Hacktoberfest, shall I add this feature?

[sibidass]

it makes sense to add this as an opt-in feature (--order)

[ibLeDy]

sure, all yours @sibidass!

Yeah, I think so
