1. Update GovernorCompatibilityBravo.sol …

   GovernorCompatibilityBravo.sol contains two `using` statements which are not used inside that contract.
   
   ```javascript
   using Counters for Counters.Counter;
   using Timers for Timers.BlockNumber;
   ```
   
   [Since Solidity 0.7.0](https://docs.soliditylang.org/en/latest/070-breaking-changes.html#functions-and-events), `using` statements no longer affect downstream contracts in inheritance hierarchy.
   
   > `using A for B` only affects the contract it is mentioned in. Previously, the effect was inherited. Now, you have to repeat the `using` statement in all derived contracts that make use of the feature.
   
   Since these statements are not used inside this contract, and cannot affect anything upstream or downstream of them inheritance, they should be safe to remove.
