feat: add needle as custom component

[JANHMS]

Overview

Really cool project, I like it. Looking forward to integrate and work with you.

• Adding Needle as a Component to Langflow.

Needle can also generate an Answer (Full RAG)

Or retrieve the chunks and further do something with it. (Let user decide what to do with chunks.)

Depends on

Depends on my other PR, where I contribute Needle to Langchain.
langchain-ai/langchain#28157

Picking this up now again, since Needle is now officially available in Langchain Community Package:

Hey @JANHMS

How are you?

Thank you for this!

This inherits from CustomComponent instead of Component which is the standard since 1.0.

ChatGPT or our Custom Component Generator template might be able to help you migrate it. You can use an example component like NotDiamondComponent.

Thanks man! Will have a look!

@ogabrielluiz I adjusted now. Works fine.

@ogabrielluiz worked on this a bit this Saturday afternoon. Should be ok now using the Component and being able to be used with other components.
