Convert JUnit XML from Bruno API Testing to CTRF JSON

A fork from junit-to-ctrf that supports empty failure and error XML elements from the JUNIT reports.

Sample JUnit report snippet from Bruno

<testcase name="testMultiplication" classname="com.example.UnitTests" time="0.020">
      <failure message="Expected 10 but was 9" type="AssertionError"/>
</testcase>

In the above case, the original junit-to-ctrf tool does not classify this as a failed test case.
