toml-rs forbids empty keys, which are allowed by the spec

[joelthelion]

The TOML spec says (https://toml.io/en/v1.0.0#keys):

A bare key must be non-empty, but an empty quoted key is allowed (though discouraged).

So I would expect the following program to work:

use toml;

fn main() {
    r#""" = 5"#.parse::<toml::Value>().unwrap();
}

But this is what I get:
thread 'main' panicked at 'called Result::unwrap()on anErr value: Error { inner: ErrorInner { kind: EmptyTableKey, line: Some(0), col: 0, at: Some(0), message: "", key: [] } }', src/main.rs:4:40

By comparison, python will happily run the following program:

import toml

print(toml.loads(""""" = 5"""))

I just noticed there is a fix in the following PR, but it was never merged: #373

[Kixunil]

This was fixed, right?

[ehuss]

Yes, this has been fixed by #373.
