Example with compressed payloads

[Scottapotamas]

Create an example project using a 3rd party compression library to shrink payloads.

Example should use a large enough 'input' structure that the compression has visible reductions in size (something like lots of floats, or text?).

• [ ] Find compression library (Heatshrink?)
• [ ] Implement with an Arduino example
• [ ] UI side for validation etc
• [ ] Minor writeup/recipie.
