Add Enable/Tri-state input to "DAQmx Tristate Output Terminal (VI)"

[heel]

The vi "DAQmx Tristate Output Terminal (VI)" lacks an input to toggle the drive state of the output.

Current version can only tristate - not enable the output. It is rare that you don't need both options.

Tri-state DAQmx

Without the enable option, it is a superfluous VI which only does half the job.

A workaround is straightforward using the technique here https://forums.ni.com/t5/Example-Programs/DAQmx-Digital-I-O-Toggling-Tristate-on-Individual-Lines-in...
