…el setting

* This means we can store the arguments and settings by letting the user do `BatchJob.new(arguments).set(options)`

* Yield the batch in `enqueue` in case someone needs info from it

* When you serialize then deserialize an activejob instance, the arguments are in the serialized_arguments field and can only be transferred over by the private method `deserialize_arguments_if_needed`. This is pretty janky, so there is probably something i'm missing

* `perform_all_later` let's us do a perform_later even with instance, which does not seem to be possible on the instances themselves

* Add spec for adding arguments and options to the batch callback

* Spacing, double quotes

* Support Ruby < 3.2 by removing the implicit key/variable syntax

* on_failure fires the first time any of the jobs fail, even once

* on_success only fires if all jobs work (after retries)

* remove unused job_id

* Allows enqueueing a job within a job, as part of the batch

* Parent batches will not complete until all child batches have been completed
