Add markers arguments in the report

[gmolveau]

Hi,

thank you for doing this lib :) Maybe my issue is related to #72 and #71.

In the case where I have markers with arguments (for traceability purposes), how can I export them in the final json report (and not have to parse the "longrepr" key) ?

@pytest.mark.requirements(issues=["41", "43"])
def test_endpoint_B():
  assert True

Thank's for your help :)
