Switch to nanosockets to minimize allocations

[megalithos]

I propose switching to nanosockets (https://github.com/nxrighthere/NanoSockets) for minimizing allocations. Currently riptide allocates quite bit of memory at least when data is received.

I might be able to implement this myself if I find the time.

Since I'm no longer actively working on Riptide I won't be able to do this, but if you do find the time, feel free to create a pull request 👍
