✨ Improved
* [18](https://github.com/sdss/cherno/pull/18) Two efficiency improvements:
* The `wait_time` is only used when a correction has actually applied. Otherwise the next iteration start immediately.
* Allow to specify a `--dynamic-exposure-time` that combined with `--max-exposure-time` can be used to set an initial short exposure time. If the field fails to solve the exposure time is automatically increased for the following iteration up to `--max-exposure-time`.
🏷️ Changed
* Set integral term for RA and Dec at APO to 0.01.
