feat: add conversation streaming

[tharropoulos]

Change Summary

This pull request includes significant changes to the dataset/indexInTypesense.ts, src/components, and src/lib/actions.ts files to streamline the data collection, conversation handling, and form submission processes. The most important changes include the consolidation of collection creation, the introduction of streaming client handling, and updates to the Form component.

Key Changes:

Data Collection and Indexing:

• Consolidated the creation of the conversation_store collection within the createDataCollection function, removing the redundant createConversationHistoryCollection function. [1] [2]
• Updated the typesense package version in package.json to ^2.1.0-2.

Conversation Handling:

• Added a streaming client for handling conversation data in EmptyChat and Form components, improving the handling of conversation streams and error management. [1] [2] [3] [4]

Form Component:

• Removed the onRequest prop from the Form component and integrated the conversation handling logic directly within the component, simplifying the form submission process.

Context and State Management:

• Exported ConversationContext from ConversationContext.tsx to allow its use in other components, ensuring consistent state management across the application.

Utility Functions:

• Updated the hitsToSources function in actions.ts to handle optional hits and return a promise, enhancing the flexibility and reliability of source extraction.
