rtrb 0.2.0

Breaking Changes

• split() has been removed, new() returns a (Producer, Consumer) pair
  • a RingBuffer cannot be owned anymore (but Producer and Consumer still can)
  • previous uses of split() can simply be removed
• new chunks module
  • simplifies the main documentation page
  • no code changes should be needed, except that ChunkError has to be imported as chunks::ChunkError
• iterator API has been changed to allow moving items in and out
  • read chunks implement IntoIterator and can be directly used in for loops or can be explicitly turned into an iterator with into_iter()
  • uninitialized write chunks provide a fill_from_iter() method that moves items from an iterator into the ring buffer
  • Default-initialized write chunks don't provide an iterator API (just use uninitialized chunks instead)
  • the previous iterator API with items of type &T, &mut T and &mut MaybeUninit<T> is not available anymore, but it can be emulated by iterating over the slices returned by as_slices() and as_mut_slices() (use chain() to iterate over both slices)
• with_chunks() constructor has been removed
  • there is no replacement, use new() instead
• reset() has been removed
  • there is no replacement
• CopyToUninit::copy_to_uninit() now returns &mut [T]
  • this is strictly speaking a breaking change, but it's unlikely that anyone relied on it returning nothing

Non-Breaking Changes

• Copy trait bound has been removed from write_chunk() (Default is still required)
• some auto-derived Debug, Eq and PartialEq implementations have been added
