1.1.0 — tinyvec, reference iterator traits and Chain

• Added support for the tinyvec crate, which is a replacement for arrayvec and smallvec without any unsafe code whatsoever.
• Added IntoRefIterator and IntoMutIterator, traits for reference iterators similar to the .iter() and .iter_mut() methods on slices.
• Added Chain, a wrapper for list-like collections which improves reallocation and insertion performance for Vec-like allocations.
