Docs: add in stream example

[willfarrell]

• Added in WebStream example
• Switched browser example to use TextDecode to match WebStream example, and prefer no polyfill first.

Note: I asked about #14 for a new library I'm working on (https://github.com/willfarrell/datastream/tree/main/packages/compress)

Closes: #14
