The changes here are from fixing stack build with LTS 15.8 (GHC 8.8.3)
to be warning-free. Most if not all come from the newer protolude
version, which adds some things like `unwords`.
So to make sure that we don't get unused import warnings with newer
stackage, this both raises the protolude lower bound and removes
these imports.
* Don't indent first line of configuration parser error messages
configurator-pg returns multi-line errors now. Alternatively,
we could indent all the lines.
* Update resolver to lts-13.29 and add lock file to repository
* Upgrade stack version
* Save cache after building dependencies only to have faster feedback loop when tests fail
* Move private functions from QueryBuilder to a separate Private module
* Move more functions over to private trying to make compilation consume less memory
* Split private in 4 modules
* Remove unused LambdaCase pragma
* Add profile to memory-tests.sh so it can find postgrest executable
* Move save dependencies before building and running tests for faster feedback loop
