Crate batch_aint_one

Batch up multiple items for processing as a single unit.

I got 99 problems, but a batch ain’t one…

Sometimes it is more efficient to process many items at once rather than one at a time. Especially when the processing step has overheads which can be shared between many items.

A worker task is run in the background and items are submitted to it for batching. Batches are processed in their own tasks, concurrently.

See the README for an example.
