Cross validation splits

[ritvikvasan]

Given a csv, compute K fold cross validation splits and save as different column names or different folders so that it is readable by Manifest datamodule. At the dry run, Filip found this functionality difficult to set up himself given the short time frame

Solution

something like

`from serotiny.io.dataframe import compute_cross_val_splits

df = compute_cross_val_splits(n=5)
`
