This PR

• it is mostly equivalent to the JS implementation, except I named the field body and not data, which seems to fit better to OTel

It looks like the OTel Python sdk only supports attributes in both span and log events. @dyladan can we include value as an attribute?

I agree body is a better term because it is used by the otel spec: https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/logs/data-model.md#log-and-event-record-definition

All language implementations in OTel are experimental so I would refer to spec before referring to any language terms used.

I've updated the JS implementation to use body.

Look great, thanks! Good catch on the data vs body. I was just looking at the JS implementation but body is a better choice.
