The new wait queue implementation doesn't allocate, and doesn't require
resizing a
VecDequeinside a lock. This should improve performance and(hopefully) make it possible to use the MPSC queue without any
allocations on no-std (once I figure out the static stuff).
Performance for blocking/yielding send is now very competitive after
switching to the new wait queue, compare the new violin plot of the integer
MPSC benchmark with violin plot with the old wait queue that i posted
in #14.
