Please update dependencies

[ezzieyguywuf]

Specifically, I am requesting:

• dlist-1.0
• QuickCheck-2.15
• aeson-1.5

I have compiled successfully using ghc-8.10.3 with no apparent problems.

If you are able to make these changes and release a new version, it will allow us to better package this in gentoo.

As of now the following bounds are all to strict, but snap works fine with disabling them:

       > Setup: Encountered missing or private dependencies:
       > QuickCheck >=2.4.2 && <2.14,
       > aeson >=0.6 && <1.5,
       > attoparsec >=0.10 && <0.14,
       > base >=4 && <4.15,
       > dlist >=0.5 && <0.9,
       > lens >=3.7.6 && <4.20,
       > mwc-random >=0.8 && <0.15
