5f87c7808c Remove the cell and trait

1b9d5e5071 Multi Producer Single Consumer channel 
An MPSC inspired by Tokio and Crossbeam. The MPSC is designed to support both single and multi core processors, with only single core implemented at this time. The allocation of the channel’s buffer is inspired by the const generic parameters that Heapless provides.
