Parse exception on service definition with whitespace

[Achllle]

I ran glint_ros on a set of ROS1 packages and got the following error.

Traceback (most recent call last):
  File "/usr/local/bin/glint_ros", line 8, in <module>
    sys.exit(main())
  File "/home/user/.local/lib/python3.8/site-packages/ros_glint/main.py", line 123, in main

    raise Exception('Unable to parse interface line: ' + repr(line))  # pragma: no cover
Exception: Unable to parse interface line: '--- '

When I ran grep -r -e "--- " in the same directory, I found that it was erroring out because of a trailing white space in a .srv file's request - response divider ---.

The error message could probably be improved / fixed as it's not part of the linting output.

This doesn't seem to be fixed yet. pip3 show ros_introspect --> Version: 0.2.2

I'm getting the exact same error.

Stepts to repro:

catkin_create_pkg test_pkg
mkdir -p test_pkg/srv
echo "--- " > test_pkg/srv/test.srv
glint_ros

I fixed the bug properly, but I did the release badly. Following your steps ros_introspect v0.2.3 works.
