Fixes #653.
Adds a new, optional feature to the
bytescrate to enable support for the Rust nightly unstableallocator_apifeature (docs).This feature is disabled by default and will only work on Rust nightly for now.
When enabled, this feature changes the default implementations of
BufandBufMutonBox<u8>,Vec<u8>, andVecDeque<u8>to support an optional second generic argument for anAllocatortype. ThisAllocatorcontrols how the type manages memory on the heap. No code paths are changed in the crate, only a new generic argument is provided to these types.When disabled, this feature incurs no changes to the crate and does not change the API or any code paths.
