Feature request: Add SSE support for restish data streaming

[NicoleStrel]

Currently, restish does not support receiving or processing data from endpoints that use the text/event-stream (SSE) content type. This limitation makes it difficult to use restish for interacting with logging or event endpoints that stream realtime data, which is a common pattern for modern APIs.

It would be very useful if restish could:

• add support for SSE, allowing the client to stream and display data in realtime as it arrives from the server.
• recognize and handle text/event-stream as an accepted response type, ensuring that streamed data is not buffered or truncated, and is presented to the user as it is received.

Examples of cli tools that support SSE:

• curl
• httpie (using the --stream flag)

Maybe something similar can be done, a flag can be added to accept sse events

Let me know what you think! Also I'm interested in working on this feature if there are no takers :)
