feat(line)!: impl From<Cow<str>> for Line

BREAKING-CHANGES: `Line` now implements `From<Cow<str>`

As this adds an extra conversion, ambiguous inferred values may no
longer compile.

```rust
// given:
struct Foo { ... }
impl From<Foo> for String { ... }
impl From<Foo> for Cow<str> { ... }

let foo = Foo { ... };
let line = Line::from(foo); // now fails due to ambiguous type inference
// replace with
let line = Line::from(String::from(foo));
```
