Initializes PartiQLData and PartiQLValueLoader

[johnedquinn]

Relevant Issues

• None

Description

• Initializes PartiQLData and PartiQLValueLoader.
• I modeled this with JDBC's ResultSet and Ion's IonReader in mind.
• I also updated PartiQLResult.Value to hold PartiQLData -- NOT a PartiQLValue.
• Note: I decided to write this in Java.

Reviewer Notice

• The second commit removes all CLI tests as the KOW branch's CLI has been completely overhauled causing this PR to fail the build. For the reviewer, I'd recommend reviewing the first commit by itself and then checking to see that I didn't accidentally delete any other files in the second commit.

Other Information

• Updated Unreleased Section in CHANGELOG: NO
• Any backward-incompatible changes? NO
• Any new external dependencies? NO
• Do your changes comply with the Contributing Guidelines
  and Code Style Guidelines? YES
