Choose start pool
🚀 Feature Proposal
As a user, after clicking on the "start new duel" FAB, I want to see a screen with the possible pools I can start with.
Motivation
In order to play a duel round, a pool has to be selected. When player A starts a new duel against player B, player A wants to have the possibility to choose the first round's pool. For round two, player B will have this possibility.
Technical Details
Requires #23
Example
Player "Banana123" decides to start a new duel. Thus, the player clicks on the "start new duel" FAB. Now the player sees a list of all his/her pools.
