Merge pull request #127 from threshold-network/pragma

Use floating pragma for IApplication and IStaking interfaces Pragma statements are fine to float when a contract is intended for consumption by contracts from another project. This is the case for IApplication and IStaking that are imported from tBTC v2 contracts. If we do not use the floating pragma, all tBTC v2 contracts would need to stay on 0.8.9 and now use the more recent Solidity versions.
