feat: add parenExpression.spaceAround

[Thristhart]

This adds spaces around the contents of parenthesis expressions. Examples:

// "parenExpression.spaceAround": false
(x.test as unknown) = 6;
// "parenExpression.spaceAround": true
( x.test as unknown ) = 6;

// "parenExpression.spaceAround": false
({ prop: 5 }).prop;
// "parenExpression.spaceAround": true
( { prop: 5 } ).prop;

// "parenExpression.spaceAround": false
const c = (1 + 1) + 1;
// "parenExpression.spaceAround": true
const c = ( 1 + 1 ) + 1;
