Use S3's range Object to fetch a chunk of bytes

You can use S3's range API to fetch a chunk of bytes from S3 object instead of the whole object/file:

            // Get a range of bytes from an object and print the bytes.
            GetObjectRequest rangeObjectRequest = new GetObjectRequest(bucketName, key)
                    .withRange(0, 9);

This can be applied to S3ClientWrapper.fetchLogFile: https://github.com/aiven/tiered-storage-for-apache-kafka/blob/main/s3/src/main/java/io/aiven/kafka/tiered/storage/s3/S3ClientWrapper.java#L75

With the new chunking approach ranged fetch queries are supported: https://github.com/aiven/tiered-storage-for-apache-kafka/blob/7e499717cdaf47af71f20aa00890b3b045b8d50b/core/src/main/java/io/aiven/kafka/tieredstorage/transform/FetchChunkEnumeration.java#L98
