TDK Lambda: Improved functionality

# Feature Description
As a member of the magnet power supplies section, I would like to to be able to do more remotely to the TDK Lambda (check name and spelling!) power supply so that I can work more effectively.

## Explanation
_{Aim to describe the ticket as if you're explaining it to someone who is new to this technology/subject area.}

[comment]: <> (FILL IN BELOW)
In the release meeting for 15.0 it was mentioned to us that it was frustrating that the available functionality for the TDK Lambda is limited compared to that provided for e.g. the Danfyski 9000s. It may be this functionality is not available for the TDK Lambda.

A recent example is that it is not possible to remotely reset the external interlocks, so they had to powercycle the device during testing, rather than simply reset the interlocks and this took longer.
