Update effectful-core bounds

[tchoutri]

@fpringle Hi! I tested it locally and the build is successful. :)

[fpringle]

Thanks @Tchouri! PR will merge when checks pass. Do you need Hackage release too?

[tchoutri]

@fpringle A hackage revision would be most appreciated ❤️

[fpringle]

Of course:

• https://hackage.haskell.org/package/effectful-postgresql-0.1.0.1
• https://hackage.haskell.org/package/effectful-opaleye-0.1.0.1

By the way, are you planning to use effectful-{postgresql,opaley} for a personal project or in production? I'd be interested to hear your experience of using it in a real project :)

[tchoutri]

Yes absolutely, it's going to be used in https://github.com/tchoutri/masna3, a project that I have designed for pair-programming and learning "production haskell". :)

[fpringle]

Very cool! I'll take a look at the project, and look forward to watching :)
