- It is now possible to pass a linked-list table to the ring-buffer with
the `new_with_table()` function or use the `new()` function for a basic
ring-buffer setup.
- A `simple_ring_buffer_table()` function was added to the read and
write ring-buffers to generate the same table as the one created by
`new()` in case the user only wants to customize the default table
options.
- RegisterUpdaters have been removed as the user now has direct access
to the table and its items if needed.
