As a user, I want to be able to give flowers to other users.

[Fweddi]

• Render a flower svg in the hands of both users' avatar
• When the user presses a certain key, their avatar's arm extends with the flower
• Each user has a different keybind
• Only one arm can be extended at any given time
• When the arm is fully extended, the flower disappears from the avatar's hand
• When the arm is fully extended, a new flower appears on their flower pile and their flower count increments.
• When the arm is fully subtended, a new flower appears in the avatar's hand
• At the end of the game, the user with the higher flower count wins
