feat: preprocessing transformation priorities

[jitingxu1]

Building upon the deliverables outlined in issue #19, the objective is to enhance the coverage of ibisml machine learning preprocessing transformations, prioritizing key areas for improvement.

Please share your favorite ML transformation for your daily ML tasks and provide additional context as to why you find it particularly useful.

Assumption

• Raw feature creation is done using ibis
• tabular data

Priority definition:

• P0: Essential tasks vital for the model development, Essential before our initial release.

• P1: Desirable tasks that can enhance the model, based on feedback and further optimization.

• P2: Additional tasks aimed at improving the model, based on feedback and further optimization.
