Fix warnings (drops Nim 1.2) (#348)
* [build] disable XCannotRaiseY hint

There are too many {.raises:[Defect].} in the
libraries that we use, drowning out all other
warnings and hints

* [build] disable BareExcept warning

Not yet enabled in a released version of Nim,
so libraries that we depend on have not fixed
this yet, drowning out our own hints and warnings

* [build] disable DotLikeOps warning

dot-like ops were an experiment that is not going
land in Nim

* [build] compile log statements in tests

When running tests, all log statements are compiled.
They are filtered out at runtime during a test run.

* [build] do not build executable when running unit test

It's already built in the integration test

* [build] Fix warnings

- remove unused code
- remove unused imports
- stop using deprecated stuff

* [build] Put compiler flags behind nim version checks

* [CI] remove Nim 1.2 compatibility
