We now fail to run hevm flatten (or hevm verify) when any source file uses a complex Solidity version pragma.

The correct way to do this would be to use the Hackage package semver-range to figure out the maximum concrete version for each pragma, what is now poorly implemented in EVM.Flatten.maximalPragma.

hevm: better parsing of pragma SemVer ranges

See #127.

We are now able to flatten the ds-proxy source code which previously
gave an error.
