Aeson problem (#74)

* Put an uppor bounds on Aeson for now

Problem: Aeson 2.0+ came out with a vuln fix. Unfortunately it is a breaking
change. This causes curl-runnings to fail to compile if you just grab a fresh
GHC installation and try to `cabal install curl-runnings`

Solution (in two steps):
1. Put an upper bounds on aeson and push a point release (0.16.4).
2. Fix the aeson compilation with CPP directives pivoting on the version of
Aeson and release a new minor version (0.17.x)

(cherry picked from commit 62fae2071c562e7cf745f3b9142225c90e432cf7)

* Bumping the incremental version of curl-runnings

(cherry picked from commit 520010af396ee0b8e2e08fb976b774f3397f1e6d)
