Loosen dependency on childprocess

[mvz]

Summary

Like it says on the tin.

Details

Allows all versions of childprocess that we can reasonable expect to work with aruba according to the childprocess changelog

Motivation and Context

Allows latest childprocess to be used with Aruba (like already is the case for 0.14.x).

How Has This Been Tested?

We're currently lacking tests for checking if the lowest required versions for dependencies still work. Other than that: Travis.

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Refactoring (cleanup of codebase without changing any existing functionality)
• Update documentation

Checklist:

• I've added tests for my code
• My change requires a change to the documentation.
• I have updated the documentation accordingly.

FYI: childprocess is semantically versioned (or at least has been since I've been maintaining it), so you should be safe all the way until 1.0.0.

[mvz]

@enkessler good to know. I'll take that into account in the next dependency update.
