20/5/2006 19:51:45 produces an error month out of range

I added test case:
{in: "20/5/2006 19:51:45", out: "2006-05-20 19:51:45 +0000 UTC"},
and it's failed with an error:

❯ go test -cover
--- FAIL: TestParse (0.00s)

This is fixed in #89 by setting the retryAmbiguousDateWithSwap ParserOption to true
