RFC: Remove TA-lib wrapper in Python

[cjdsellers]

As part of the ongoing effort to port core functionality to Rust, we plan to minimize the amount of code maintained in Python.

This RFC is to provide advance notice to users relying on the current TA-lib wrapper in Python that it is now deprecated and marked for removal.

In the future, we may introduce a similar wrapper implemented in Rust, with Python bindings provided via PyO3.

We welcome any thoughts and feedback on this plan!

this seems to be a maintained rust binding with some pyo3 as well (I don't know the details of how it works though, just looked at various talib rust possibilities) : https://crates.io/crates/talib/0.1.2

As @faysou mentioned,there are many talib based on Rust or Polars, which are faster in computation, making it unnecessary to introduce additional dependencies.

[faysou]

The talib dependency is inside the rust dependency, it's still there.

@faysou Some are developed based on talib, while others are completely redeveloped to no longer rely on talib.Simpler factor development is more important compared to talib.
