PARQUET-2050: Expose repetition & definition level from ColumnIO

[sunchao]

Make sure you have checked all steps below.

Jira

• My PR addresses the following Parquet Jira issues and references them in the PR title. For example, "PARQUET-1234: My Parquet PR"
  • https://issues.apache.org/jira/browse/PARQUET-XXX
  • In case you are adding a dependency, check if the license complies with the ASF 3rd Party License Policy.

Tests

• My PR adds the following unit tests OR does not need testing for this extremely good reason:

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

For rationale, please check the JIRA https://issues.apache.org/jira/browse/PARQUET-2050. Not sure where should I put those in the PR description.

@shangxinli @ggershinsky @gszadovszky could you review this? Thanks!

[shangxinli]

@gszadovszky Is there any concern from you?

[gszadovszky]

I am fine having these methods public if it is required for our users. Meanwhile, since it is public, it would be great having the proper javadoc comments for them.

[sunchao]

Thanks for the review @gszadovszky . Added.

[shangxinli]

LGTM. After fixing the checks failure, we can merge.

[sunchao]

Thanks @shangxinli and @gszadovszky . Do you know how to see the details for the check failures? I opened the link and it just shows "This check failed".

[sunchao]

Let me trigger the CI again to find out why.

[gszadovszky]

I don't know why we had such failures but they were not only for this PR. As they are passing now I'm merging this PR.
