Egregore BITCOIN lottery

• Users approve contract to spend BITCOIN then call sacrifice to pay penitence and enter. One token = one chance.
• End time is 4/20/2024 00:00:00 UTC (+/- 900s for miner interference)
• LINK should be provided before this date to power the drawer (< 2 LINK @ current prices)
• Draw closes after 4/20/24 when anyone calls beginCeremony
• Chainlink VRF will set a random number on the contract
• Anyone can then call payout which will pay the lucky winner their stake + half the pot. Other half of pot goes to burn address 0x...dEaD
• Safety function for owner to retry beginCeremony if LINK was not sufficient or VRF callback failed

To run forge test you'll need to create a .env file containing your RPC endpoint, eg,
