Update to lts-12.10, support ghc 8.4, and aeson 1.3.
Don't fully understand the need for the MonoLocalBinds language extension, which was not needed before but now ghc complains if it's not included, but I've tested it and it does work. All the rest of the changes are straightforward AMP changes and dep updates. Removed fgl from stack.yaml because it seems that indirect dep no longer needs to be specified for stack to build. Added custom-setup stanza since stack now warns without one. This commit was sponsored by Trenton Cronholm on Patreon.
