Thanks for your contribution to [Apache Tika](https://tika.apache.org/)!
Your help is appreciated!
Before opening the pull request, please verify that
* there is an open issue on the [Tika issue
tracker](https://issues.apache.org/jira/projects/TIKA) which describes the
problem or the improvement. We cannot accept pull requests without an issue
because the change wouldn't be listed in the release notes.
* the issue ID (`TIKA-XXXX`)
- is referenced in the title of the pull request
- and placed in front of your commit messages surrounded by square
brackets (`[TIKA-XXXX] Issue or pull request title`)
* commits are squashed into a single one (or few commits for larger changes)
* Tika builds and unit tests pass with `./mvnw clean install` (`clean test`
alone cannot resolve the pipes plugin zips)
* if you used a generative AI tool: follow the [ASF Generative Tooling
Guidance](https://www.apache.org/legal/generative-tooling.html) (`Generated-by:
<tool>` in the commit message), and consider running the pre-flight in
`.skills/devs/pr-review/SKILL.md` — fix what it finds; don't paste its report
here
* there should be no conflicts when merging the pull request branch into the
*recent* `main` branch. If there are conflicts, please try to rebase the pull
request branch on top of a freshly pulled `main` branch
* if you add new module that downstream users will depend upon add it to
relevant group in `tika-bom/pom.xml`.
We will be able to faster integrate your pull request if these conditions
are met. If you have any questions how to fix your problem or about using Tika
in general, please sign up for the [Tika mailing
list](http://tika.apache.org/mail-lists.html). Thanks!

> We rolled out the onenote stuff to a customer, and performance degraded a

> I haven't gotten access to the customer documents to test on but measuring
> the test docs I've been working with had it making over 500 gc calls in 1000
> parses of the section-2 document, which contains a large image. Anyway, it
> looks like storing an image as List<Byte> is real bad, compared to byte[]. PR
