Bug - Column names with a only capital letters are not surrounded by quotes on deparse.

[ateszki]

Example

const parsed = parse('select "A" from "table_name");
const deparsed = deparse(parsed);
// departed is now 'select A from table_name'

const parsed = parse('select "AA" from "table_name");
const deparsed = deparse(parsed);
// departed is now 'select AA from table_name'

I think the fix would be to change the const needsQuotesRegex = /[a-z]+[\W\w]*[A-Z]+|[A-Z]+[\W\w]*[a-z]+|\W/; to
`const needsQuotesRegex = /[a-z]+[\W\w][A-Z]+|[A-Z]+[\W\w][a-z]+|\W|[A-Z]/;
