Revert PR #471 - add DST to sunrise/sunset

Browse source 
The DST code has not yet been fully tested, the upcoming movement
refactor is upon us and it will integrate with the micro timezone
library anyway. Revert it so that next can be merged into main.

This reverts commit 0cc28b9811, reversing
changes made to 337864eb54.
