feat: migrate decoders to protobuf

[kruskall]

Motivation/summary

This is a small PR to fix an issue with aggregation tests.

Also bump the apm-data library and reenable the broke tests.

Checklist

- [ ] Update CHANGELOG.asciidoc
- [ ] Update package changelog.yml (only if changes to apmpackage have been made)
- [ ] Documentation has been updated

For functional changes, consider:

• Is it observable through the addition of either logging or metrics?
• Is its use being published in telemetry to enable product improvement?
• Have system tests been added to avoid regression?
