Proveably Random Raffle Contract

About

This code is to create a provably random smart contract lottery.

What we want it to do

1. Users should be able to enter the raffle by paying for a ticket. The ticket fees are the price the winner receives.
2. The lottery should automatically and programatically draw a winner after a certain period.
3. Chainlink VRF should generate a provably random number.
4. Chainlink automation should trigger the lottery draw regularly.

Testing Raffle contract

1. Write deploy scripts
2. Write test scripts
