Potential segfault in the time crate

[s-tar]

Hey!

We use goose in our project and during cargo deny check we found out that goose use chrono dependency, which has security vulnerability. Here is detailed description: https://rustsec.org/advisories/RUSTSEC-2020-0071

Solution is very simple:
Update dependency for chrono to next
chrono = { version = "0.4", default-features = false, features = ["clock"] }

Do you mind to do that? Thanks.

Regards, Sergii.
