• Add functions to apply external compression filters on datasets in the write kernel: SZ3, ZFP
• Add steps to output filter configuration setting, calculated total data size after compression, and compression ratio in the write kernel and corresponding csv file
• Add functions to retrieve filter information and output it in the read kernel and corresponding csv file
