Generate disjunctions in parentheses

[sdboyer]

Currently, the following input:

U1: "foo" | "bar" | "baz" @cuetsy(kind="type")
U2: 1 | 2 | 3 @cuetsy(kind="type")
U3: {
    listU: [...(dep.U1 | U2 | U1)]
} @cuetsy(kind="interface")

will produce the following output (modulo my comment):

export type U1 = 'foo' | 'bar' | 'baz';

export type U2 = 1 | 2 | 3;

export interface U3 {
  listU: dep.U1 | U2 | U1[]; // straight up inccorrect - needs parens
}

I think the simplest solution here is just to always generate parentheses on output. It's not the tidiest, but as long as the output is correct, i think that's sufficient.
