feature: ISC License (#117)

# Changes

Adds ISC License. Based on discussions with @Siilwyn and @WesselSmit.
Decided CLA is too much of a hassle to protect Voorhoede IP. So
simplified to a permissive modern license.

# Associated issue

Resolves #69

# How to test

Review license and verify it [provides what we
want](https://choosealicense.com/licenses/isc/).
