A client for the GMT mount control system.
There are a few mount controller and driver models to choose from.
The model selection is set with the `MOUNT_MODEL` environment variable.
Possible values for `MOUNT_MODEL` are:
* `MOUNT_FDR_1kHz`: FDR version of the controller and driver sampled at 1kHz
* `MOUNT_PDR_8kHz`: PDR version of the controller and driver sampled at 8kHz
* `MOUNT_FDR_1kHz-az17Hz`: PDR version of the controller and driver sampled at 8kHz with a notch filter at 17Hz in the controller
