Wildcard to return an array of left over segments

## Actual

```js
const route = matchit.parse('/foo/*');
matchit.exec('foo/bar/baz', route)

// returns
{
'*': 'bar'
}
```

## Expected

```js
const route = matchit.parse('/foo/*');
matchit.exec('foo/bar/baz', route)

// returns
{
'*': ['bar', 'baz']
}
```

Not sure, if their is any specific reason that it returns a string with first segment and not all the segments as an array

Start by reading the matchit.parse and matchit.exec entry points used in the example to understand how wildcard segments are captured. Done means matching /foo/bar/baz against /foo/* returns {'*': ['bar', 'baz']} rather than only the first segment; check the project's existing behavior around wildcard matches before changing it.
