Code style

[kulvait]

Hi,

thank you for this library — I’m currently building an ImageJ plugin for Zarr on top of it.

While working on ReadOnlyZipStore, I focused on performance improvements. I rewrote the directory listing logic and avoided apache IO logic which provide a substantial speedup. However, chunk reading is still inefficient because it relies on sequential streaming via Apache Commons, so there is more room for improvement there.

On a separate note, I noticed that the repository does not seem to include an actual code style configuration (the .idea/codeStyles is empty). It would be very helpful to have a defined formatter. I experimented with Spotless + Eclipse formatter, but the result still introduces many formatting changes compared to the current codebase.

Before opening a PR, I’d like to avoid large formatting-only diffs. If you could share or export your code style, it would help keep contributions consistent.

Thanks!

Please have a look if it is possible to edit files in https://github.com/kulvait/zarr-java/tree/zip/styles so that it is possible to format by maven spotless like:

<plugin>
  <groupId>com.diffplug.spotless</groupId>
  <artifactId>spotless-maven-plugin</artifactId>
  <version>3.4.0</version>
  <configuration>

      <eclipse>
        <file>${project.basedir}/styles/eclipseStyle.xml</file>
