* Add EQC profile
Don't run EQC tests, unless specifically requested e.g. `./rebar3 as eqc eunit --module=leveled_eqc`
* Remove eqc_cover parse_transform
Causes a compilation issue with the assertException in leveled_runner
* Allow EQC test to compile
EQC only works on OTP 22 for now, but other tests should still work on OTP 22 and OTP 24
* Add more complex statem based eqc test
* Add check for eqc profile
