Subject: [PATCH] Allow invalid UTF-8 for `roc format` argument

Presumably with a new version of clap that was introduced, we must now
specify that invalid-utf8 is permitted in order to run `matches.values_of_os`
as we do on line 174 of cli/src/main.rs:

```rust
        Some((CMD_FORMAT, matches)) => {
            let maybe_values = matches.values_of_os(DIRECTORY_OR_FILES);
```

Otherwise, clap panics:

```
thread 'main' panicked at 'Must use `Arg::allow_invalid_utf8` with `_os` lookups at `DIRECTORY_OR_FILES`', cli/src/main.rs:174:40
```
