fix: remove dependency on Q

[talentlessguy]

Brief Summary of Changes

This PR removes a deprecated and outdated Promise library - Q. And replaces it with Promise API and built-ins.

deprecation notice from q:

You or someone you depend on is using Q, the JavaScript Promise library that gave JavaScript developers strong feelings about promises. They can almost certainly migrate to the native JavaScript promise now. Thank you literally everyone for joining me in this bet against the odds. Be excellent to each other. (For a CapTP with native promises, see @endo/eventual-send and @endo/captp)

The source now uses the following methods:

• new Promise() - supported since Node 0.12 and in all browsers (except IE11)
• Promise.resolve - same as above
• Promise.reject - same as above

What Does This PR Address?

• GitHub issue (Add reference - #XX)
• Refactoring
• New feature
• Bug fix
• Adds more tests

Are Tests Included?

• Yes
• No, the tests logic didn't change
