Fix the PC Viewer to support multi-dataset PHATE embedding

[edyoshikun]

This PR cleans up the PC viewer to support multi-dataset view of PHATE and PC.

Here we ad a configurable .yml file to feed the FOV, tracking, and embeddings information. Additionally, we support configurable PHATE parameters and number of PCs.

Thank you @edyoshikun!
I am getting the following error while using the script:

You reported that the viewer would freeze for the datasets your were working with.

@Soorya19Pradeep seems like this is now working. Can we close and merge this PR to main?

I am using max projected data now and a smaller number of FOVs. It works well for this case, except it is slightly slow to respond sometimes. But it is workable.

Thanks @edyoshikun . I currently just have one issue with the widget which has a very easy workaround. The plotly widget stores information in my web browser, which leads to it breaking if I run the same code again. For instance, when I use the lasso tool to annotate clusters once in a specific PC space, then I close down the port. Then rerun the code and try lasso again, it would not do a great job and shows a combination of something I am trying to do and from the past annotations. It is not very reproducible. I read that this is a feature from Plotly, and I can open a new browser window to fix this. I was just unsure if there is a workaround for that through the code.
