raise `optparse-applicative` upper bound

[peterbecich]

Can we raise the upper bound on optparse-applicative?

The test suite produces the same error with optparse-applicative 0.15 and 0.17:

Error: cabal: Tests failed for test:hypsrc-test from haddock-2.27.0.

The other tests pass with both 0.15 and 0.17.

If optparse-applicative-0.17 is allowed, I think it will be easier to use haddock-library with Nix. optparse-applicative is on 0.17 in nixpkgs-unstable: https://search.nixos.org/packages?channel=unstable&show=haskellPackages.optparse-applicative&from=0&size=50&sort=relevance&type=packages&query=optparse-applicative Using the alternative optparse-applicative_0_15_1_0 may have other issues.
