Allow template-haskell 2.17, 2.18

[sorki]

With a bit of CPP for backwards compatibility.

I was just about to submit a PR, word-for-word the same as this one except for one type variable name.

@sorki I just did some tests and found that the template-haskell-2.18.0.0 also works so the upper bound can be bumped further:
- template-haskell >= 2.11 && < 2.19
This would allow freer-simple to work with the latest version of template-haskell.

@lexi-lambda Could you please process this PR and make a new hackage release if it looks good? It is needed for GHC 9.0.

Nice! I've bumped the bound to allow 2.18 as well.

Thanks, and sorry about the delay.

I’ve now released this to Hackage as freer-simple-1.2.1.2.
