[PARQUET-1717] Convert i16 thrift to INT16 logical type instead

[ebrard]

Make sure you have checked all steps below.

Jira

• My PR addresses the following PARQUET-1717

Tests

• My PR does not need testing for this extremely good reason: No new functions were added

Commits

• My commits all reference Jira issues in their subject lines. In addition, my commits follow the guidelines from "How to write a good git commit message":
  1. Subject is separated from body by a blank line
  2. Subject is limited to 50 characters (not including Jira issue reference)
  3. Subject does not end with a period
  4. Subject uses the imperative mood ("add", not "adding")
  5. Body wraps at 72 characters
  6. Body explains "what" and "why", not "how"

Documentation

• In case of new functionality, my PR adds documentation that describes how to use it.
  • All the public functions and the classes in the PR contain Javadoc that explain what it does

Thanks for taking a look at this! Could you please also add a test case too?

[ebrard]

Will do.

@nandorKollar I added a simple test for this specific conversion, I hope that's the right approach
