Review Comment:
This is needed to save case sensitive [S3 write/delete tag
keys](https://github.com/apache/iceberg/blob/master/docs/integrations/aws.md#s3-tags)
for objects.
There is a thread in `general` channel on this, let me add you there:

I have removed the case insensitive comparator from the Treemap as well.
