Small addition to the original 2.3.3 release

This release includes a change that allows dex-test-parser to parse additional dex files packed by buck as assets into jars.
Original release: https://github.com/linkedin/dex-test-parser/releases/tag/2.3.3

Custom annotations support and argument parsing

A minor change:

• added support for custom test annotations when a test is marked with something else except @test (see example from StackOverflow: https://bit.ly/2IOxfad)
• added argument parsing with kotlin-argparser
  • and now it can output tests to stdout if output dir is not provided
