ION-281 Update ionic_langchain to new SDK

https://github.com/ioniccommerce/ionic_langchain should be using the new https://github.com/ioniccommerce/ionic_sdk_python

You can use https://github.com/ioniccommerce/demobot-agent-langchain to test

@owensims1 is this still relevant? I see it commented out in the demobot

there's gonna be two ways to integrate a langchsin tool-- first is using the sdk which is how i had been using since the beginning.

this is the second, where after we built the openai plugin route, we noticed that langchsin has an integration solution for this, but i found it to not work anywhere near as well as advertised, and i lost interest in pursuing at the time.

so, feel free to remove entirely for now until we can bring it back in an official capacity. let's stick with the sdk connection that affords us a bit more control

@owensims1 this is working locally; PTAL and we can chat in our 1:1 about what to tidy it up to make it mergeable

[owensims1]

lgtm. good start. will want to get error handling in and we can also start hammering it from a usability standpoint tomorrow
