v0.8.0

0.8.0 - 2021-05-07

This release significantly improves the support for Solidity 0.8 and adds detectors for 'unused-return-transfers', 'dead-code', and 'write-after-write'. Slither now supports multiple compilation units which solves many issues when using hardhat.

Thanks @sobolev-igor for his contribution!
