Prettyprint option for expr.toString()

[ylieder]

As documented, the toString method of an expression surrounds every sub-expression with parentheses. For pretty printing, it would be good to have a pretty option in the toString method, putting only required parentheses.

For example:

const exprString = Parser.parse('3 + ((4 - 5) * 12)').toString(); 
const exprStringPretty = Parser.parse('3 + ((4 - 5) * 12)').toString({pretty: true}); 
// exprString: (3 + ((4 - 5) * 12))
// exprStringPretty: 3 + (4 - 5) * 12
