[FEA] Allow dynamic slicing using ListSlice operator

[sararb]

Slicing sequence of past interactions can vary between rows based on a specified rule (such as taking 80% of the original sequence, taking interactions from the last hour.)

Describe the solution you'd like

The desired solution is to link the Slicing operator to a column specifying the length (number of items) to consider for each row.

Describe alternatives you've considered A clear and concise description of any alternative solutions or features you've considered.

Additional context Add any other context, code examples, or references to existing implementations about the feature request here.
