RFC 3339 support for both Marshal and Unmarshal. (#204)

* RFC 3339 support for both Marshal and Unmarshal.

* Post merge cleanup

* Update request_test.go

Co-authored-by: Quetzy Garcia <[email protected]>

* Spelling

* Update request.go

Co-authored-by: Quetzy Garcia <[email protected]>

* Simplify the ISO 8601 logic. No need for the const rfc3339TimeFormat use time.RFC3339 directly.
