[FEATURE] Custom Document Splitter

[dentro-innovation]

Describe the feature you'd like
I want to have a document loader for the doc store where I can upload a text file (in the future PDF would also be great) and I can define my own logic on how to split it.

Currently we only have the custom document loader, which doesn't allow uploading files directly but needs to fetch them via API calls.

You can use custom document loader, and specify your own JS logic to split it:

But I can't upload files via the UI using the custom document loader, can I?

ah okay, I see what you mean, existing loader + custom splitter
