Investigate Uint8Array as replacement for Buffer

[viglucci]

We should look into using Uint8Array as an alternative to Buffer since from what I am reading it is supported in both Browser & Node runtimes.

Motivation

Simplify usage of rsocket-js in browser environments.

Desired solution

Replace Buffer usage with Uint8Array.

Considered alternatives

Continue using Buffer and provide stronger guidance that Browser use-cases will require polyfill.
