This is an implementation of a multi producer, multi reader lockless ring buffer utilizing the new generics available in go 1.18. Instead of passing typeless interface{} which we have to assert or deserialized []byte we are able to pass serialized structs between go routines in a type safe manner.

=> Change reader, writer index logic to now mean that the value of the index is the last value read/written to. => Change loop operations on readers to now yield on first indication write is not currently possible. Replace loop and if statements with goto to retry write on failure reducing branching on successful and yielding write operations. This improves speed significantly in concurrent environments. => refactor buffer itself to use consistent naming for reader value => make tests use same implementation to ensure read/write order is consistent => Update readme with new benchmarks
TODO:
Allowed removing consumers and determining if they are active via comparison with nil. Pointer Array and skipping comparisons on nil has sufficient speed-ups to allow approach.
I am curious if this supports multi-process cases where the ring buffer is shared memory (either shared mmap or shmem). Have you tested this, is it meant to be supported?
