Issue Description
When using agentops.end_session(), the function requires a token parameter that isn't documented in the client implementation.
Steps to Reproduce
import agentops
agentops.init()
# ... code that uses agentops ...
agentops.end_session('Success') # This fails with TypeErrorError Message
TypeError: end_session() missing 1 required positional argument: 'token'
Root Cause
The end_session() function in agentops/__init__.py requires both a span and token parameter, but the client implementation in client.py only requires an end_state parameter.
The issue is that __init__.py is calling the legacy version of end_session() which requires both parameters, while the client implementation has been updated.
Proposed Solution
Update the end_session() function in __init__.py to match the client implementation, removing the token parameter requirement.
