Doobie now recommends that you don't use RC6 and wait for RC7. I'll close this PR

https://github.com/typelevel/doobie/releases/tag/v1.0.0-RC6

Warning: We have an issue in this release related to automatic derivation not using explicitly defined instances (See typelevel/doobie#2104). Please refrain from using this release and skip to 1.0.0-RC7 when it is out.
