bot: Link duels command to Discord User, create my_duels command

[rsodre]

Depends on #2, #5

Tasks

• [ ] Adapt the duels_by_duelist command (#2)
  • [ ] Allow a special input
  • [ ] Check if the Discord User who sent the command is linked to a duelist addresses (#5)
  • [ ] Check if the Challenge duelist_a and duelist_b addresses are linked to a Discord User Id (#5)
  • [ ] Add a tag to each user to the notifications, when linked
• [ ] Create the my_duels command. Exactly like live_duels, but filters by duelist (duelist_a or duelist_b). Please do not to duplicate the whole command, create 2 entry points that generate the same result.
  • [ ] Check if the Discord User who sent the command is linked to a duelist address (#5)
  • [ ] If not, display a message explaining how to link (TBD), and exit
  • [ ] It must function exactly like the duels_by_duelist command (#2)
  • [ ] As duelist_address, use the player's duelist addresses linked to their Discord account
  • [ ] Input: state as a list of options from the ChallengeState enum, used to filter duels
  • [ ] Input: page (optional)

The ChallengeState enum:

enum ChallengeState {
    Null,
    Awaiting,
    Withdrawn,
    Refused,
    Expired,
    InProgress,
    Resolved,
    Draw,
}

Notes

• Please do not duplicate functionality!
• When displaying a message with the same contents as other messages (my_duels and duels_by_duelist, my_turn and live_duels for example), extract the message-building part to a new function that can be called by both.
