Add CytoTable module to have csv and npz support

[axiomcura]

What other formats might you want to use with CytoSnake? If CytoSnake will be tightly coupled with the SQLite format, consider providing those details upfront via documentation.

CytoTable does not only convert sqlite to parquet files but also npz (DeepProfiler) and csv (CellProfiler)

Currently the CytoTable module in CytoSnake only takes sqlite files as input.

@axiomcura , @gwaybio - Yes, this is correct. CytoTable will attempt to navigate a provided source data directory for nested CSV's or SQLite data and concatenate or join the data together in the results.

CytoTable expects CSV files to be within a directory while CytoTable expects NPZ files to only be a file path
