Add new Release to platformio

[dbambus]

Hey @tzapu,

Thank you very much for your Release 2.0.17, it is absolutely brilliant and I already intend to use it in my repo for a word clock. However, for this project I use platformio and it would be super if the release could also be managed by their repo system.

The previous release 0.16.0 is already there, but could you update it to the latest release as well?
