Develop 3.1 eqc (#339)

* 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
