BatchSpanProcessor class

A SpanProcessor that batches spans before export.

This processor collects finished spans in a queue and exports them in batches at regular intervals, improving efficiency compared to exporting each span individually. Spans are added to a queue when they end, and periodically sent to the configured exporter in batches according to the configured schedule.

The batch behavior can be tuned using BatchSpanProcessorConfig to control batch size, queue limits, and export timing.
