invalid grammar production 0alse

[tpdenk]

SELECT 0%0alse crashes the application, but must not be parsed

[tpdenk]

test case:
internal/parser/issue107_test.go

func TestIssue107(t *testing.T) {
	NegativeTest{
		Name:  "issue107",
		Query: "SELECT 0%0alse",
	}.Run(t)
}

doesn't fail

it seems like that can't be the fallback for everything, because that allows 0alse to be parsed as 0 (numeric) and then simply alse as another expression.
This is not a valid grammar production.
