Handle too many spaces after parenthesis

In #54 we added required spacing inside parenthesis, but it does not check if there is more than one space.

I'd like to be able to transform this:

```php
if ( isTrue() ) {
```

into this:
```php
if ( isTrue() ) {
```

Start with the spacing change introduced in issue #54 and find the PHPCS sniff that handles required spacing inside parentheses. Reproduce the shown PHP example, then verify the completed change transforms multiple spaces to one while preserving the required surrounding spaces.
