In this commit the vec backing the buffer is swapped for an array.
Criterion benchmarks were added to compare the perf to make sure it has
not made it worse. The vec implementation has been removed after the
benchmarks done locally
- This commit allows `RecordBatch` to be created directly from event
store. It means we can avoid cloning events and avoids creating
intermediate vec. To achieve that, there's a new method
`as_record_batch` that's been added with a trait bound `ToRecordBatch`
that events are expected to implement.
- Minor tidy ups (renaming methods) and added test

This commit introduces basic store for sys events and the backing ring
buffer. Since the buffer needs to hold arbitrary data, it uses `Box<dyn
Any>`
