Fixes #11

[mitnk]

Replaced env::home_dir() with dirs::home_dir() as rustc suggests:

warning: use of deprecated item 'std::env::home_dir': This function's behavior is unexpected and probably not what you want. Consider using the home_dir function from https://crates.io/crates/dirs instead.

    |                                     ^^^^^^^^^^^^^
    |
    = note: #[warn(deprecated)] on by default

For the CI fails, I don't know the reason. Master fails too #10. Could you help to have a check?

This PR is ready for another review. Thanks!

Can you remove the version bump? I usually do that in another commit.

Looks good otherwise, I'll merge as soon as that's removed 🐼
