https://developers.hubspot.com/docs/api/marketing/transactional-emails

This maps to a POST /marketing/v3/transactional/single-email/send

Usage Example:

    props := make(map[string]string)
    props["favoritecolor"] = "green"
    res2, err := client.Marketing.Transactional.SendSingleEmail(&hs.SendSingleEmailProperties{
        EmailId: "xxxxxxxxxxxx",
        Message: &hs.SendSingleEmailMessage{
            To:     "testing@example.com",
            SendId: id.String(),
        },
        ContactProperties: &hs.Contact{
            FirstName: hs.NewString("Stephen"),
        },
        CustomProperties: props,
    })

Addressed all requested changes with fixes.

Updated sample at the top of this PR to reflect naming schemes.

Re-ran tests against API and everything appears to still be working.
