Possible to implement CSDI as a forecasting model for POTS data

[WenjieDu]

1. Feature description

Although, in the CSDI paper, the authors discussed using the model for time series forecasting, their experiments and scenarios are for complete time series. However, the model is possible for POTS forecasting.

2. Motivation

Make CSDI a forecasting model in PyPOTS.

3. Your contribution

I'm currently overloaded. If anyone is interested in this task, please discuss it below to see if you can take it.

The CSDI model has been included in PyPOTS as an imputation model, so necessary modules are all available already.
