multiple inputs with session support

[yaowei520]

Describe the bug

when I use multiple inputs with session, There was a Error:
Error processing message: Cannot provide both a session and a list of input items. When using session memory, provide only a string input to append to the conversation, or use session=None and provide a list to manually manage conversation history.

Debug information

• Agents SDK version: v0.2.0
• Python version (Python 3.10)

Expected behavior

I want to use the multiple inputs with session in agent

I want to use the multiple inputs with session in agentr or I can assign a specific input to the session in the case of multiple inputs

Hi, this is the comment made by the author of the PR that added the Session feature:

# Validate that we don't have both a session and a list input, as this creates
# ambiguity about whether the list should append to or replace existing session history

We can choose a way to deal with it, using a default behavior or setting a new parameter in the Session object for example.

@seratch , if you think this feature should be implemented, I would be happy to collaborate on a PR, let me know.

Would really like to see this feature as well! 👍

I've seen the Sessions feature last day and were motivated to migrate my own history handling to the Sessions handling of the SDK because it's ways smoother.
While I were implementing this I also came across the bug that we can only add simple text and not multiple inputs like text and image.
