add Smoothed Heiken Ashi

[MSLight]

Hello, I would like to request a new feature for this project. I would appreciate it if you could add the Smoothed Heiken Ashi indicator to the available indicators in the repository.

This indicator is a useful tool for detecting the trend direction and strength, as well as the support and resistance levels. It is based on applying a moving average before and after the heiken ashi conversion of the price data.

You can find more information about this indicator and how to calculate it in these web pages: Link 1, Link 2, Link 3.

I think this indicator would be a valuable and would benefit many traders who use this project. Thank you for your consideration and your hard work on developing.

Best regards.

Thanks for contributing ideas! ❤️
We usually don't implement community-created indicators, but I'll add this to the backlog and take a closer look later.
To set some expectations, given other priorities in our roadmap, we won't be able to review this for a long time.

We also have several features in the pipeline that will make it much easier to create your own custom indicators.
