Focuser Primaluselab Sesto Senso 3 requires adaptation of the driver

[fscbr]

The Primalucelab model SESTO SENSO 3 rest api differs from the implemented for model SESTO SENSO 2.
Instead "{"req":{"cmd":{"MOT1":{"STEP":%d}}}}" "{"req":{"cmd":{"MOT1":{"GOTO":%d}}}}" needs to be sent to move the focuser motor.
The response as well needs to look up the tag GOTO instead of STEP.

To get the motor status a command "{"req":{"get":{"MOT1":{"STATUS":{"MST":""}}}}}" needs to be sent before the checking the response GET_MOT1_MST for the token "stop".

I tested most of the other focuser rest api requests using postman, they seem to be unchanged compared to the implemened focuser requests.
The rotator I can't test.

I made the required changes for my local indigo server version. If you want to upgrade the driver, I can sent you a patch file or the modified code file.
