Twilio Support for RCS Title and Description Text in Rich Card

Twilio will now support RCS Title and description text in twilio/card. We will support backwards compatability to ensure no existing templates fail to deliver based on channel limitations. 

No changes will occur in WA translations. 

• Twilio supports RCS title via the title field in twilio/card
  • Up to 200 characters for RCS title
  • Twilio will translate twilio/card title to description if twilio/card title is greater than 200 characters
• Twilio supports RCS description with the body field in twilio/card
  • twilio/card subtitle will also be appended onto the body to form RCS description
