Add support for patient email

[Brian Cragun]

Add support for patient email to telecom

If PID.13 (home) or PID.14 (work) has a value in XTN.4 create a ContactPoint element.
Example:

{
        "system": "email",
        "value": "[e-mail]",
        "use": "home",   
        "rank": 1
      }

• use will be "home" for PID.13, "work" for PID.14
• rank will be included if there is a value in XTN.18

At this time, no need to check if XTN.2 has NET or XTN.3 has Internet or X.400. Although these would be expected. If there is any value in email, we will capture it. In the future if validation of email format is required, it can be added.
