Fix toolcalling timestamp (#22)

* Fix toolcalling timestamp bug

- 0.1.4 server started returning completed_at and started_at timestamp, but it's not compliant with the OffsetDateTime format that SDK expects. This is causing the agentTurnResponseStepComplete to be missing/incorrectly type-casted to unknown. This patch will ignore the timestamp for now, at least until 0.1.5 release next week when the format is corrected on server side.

* Update readme and bump version

 - Remote Inferencing: Perform inferencing tasks remotely with Llama models hosted on a remote connection (or serverless localhost).
 - Simple Integration: With easy-to-use APIs, a developer can quickly integrate Llama Stack in their Android app. The difference with local vs remote inferencing is also minimal.
