The CHANGELOG is out of date

[haarts]

Steps to reproduce:

1. Look at CHANGELOG.md, observe it end at a 1.10 release.

What should happen:

1. It should contain the 1.13 release

What happens:

1. The tinker_python repo floats the dependency of this SDK, this is unwise and breaks now. I headed over to this repo to see what changed and found a stale changelog. 😞

SDK version and environment

• Tested on 1.13.1
• [x ] Sandbox
• Production

Python 3.7, Ubuntu 19.10

This is a shame as it makes developing using Bunq's SDK quite a bit more difficult.
