Enabled parsing for (T/) tag instead of (t/) tag as (t/) is still reserved for optional tags for now
Added telegram username field to Person class
Telegram username field can be null, which represents that user did not input a telegram handle for that contact (perhaps can move towards using an Optional class to better represent the value where it could possibly be null)
Added backend logic of storing telegram username to model and storage, as well as retrieving it from json on startup
Added telegram username to GUI beside the name of the contact
Things to work on
Add test cases
Check for bugs
Potentially delete (t/) tags feature to allow telegram username to use (t/) tag instead of (T/)
For #56
