Add Support for Batch-Normalization to Streaming Log Outputs #59
Description
Related to mixed non-batch and batch usage from Issue #58.
We see that https://github.com/viant/mly/blob/v0.19.x/service/stream/service.go#L91 service.stream.(*Service).Log() sends logs with the input directly copied into the logged entry.
This causes some issues for a use case of using the logged outputs to feed into a GBQ (or any structured, list-capable schema) table - since the non-batched vs batched inputs have differing types (scalar vs. list, respectively), the same log entry won't work without some form of manipulation.
The main question is if this should be an option enabled on the streaming or if this is strictly a concern for our use case to address.
