redeem coins

[2i2i]

if Host Algorand account has 0 ALGO, then Host cannot receive any amount less than 0.1 ALGO

if Host Algorand account is not opted into some ASA, Host cannot receive that ASA

if a Host cannot receive the coins they should, the coins stay in the smart contract

the Host should be able to redeem those coins

• smart contract method to redeem (1m1)
• cloud function to check whether Host got its coins; if not, update redeem db table (1m1)
• dart transaction code to redeem coins (1m1)
• 'redeem coins' page: shows a list of tiles, one for each ASA that is due to the user with a button that triggers the above transaction method
