TPG300: fix and re-test switching functions on hardware

[Tom-Willemsen]

Where?

TPG300 IOC

How?

When tested on hardware, sending new switching functions did not work. This should be made to work for RIKEN.

See #7205 (comment) for details including error message - it looks like the command is not quite right as streamdevice is complaining about bad response format.

To test TPG300:

• Find an appropriate TPG300 to test on (e.g. ask instrument scientists if you can borrow an instrument temporarily)
• Note what the TPG300 is currently reading before any changes
• Back up old db/protocol/opi on the instrument
• Deploy changes to protocol/db/opi
• Run new TPG300 ioc.
• Verify that functionality works (e.g. try changing switching functions, verify that readbacks are the same as they were on previous version, etc)
• Once testing is complete, put IOC back to how it was
• Once ticket is reviewed, inform scientists that test is complete

Reproducible?

Yes

To Reproduce

• Run IOC against hardware

Acceptance criteria

• Issues noted in RIKEN/TPG300: Test TPG300 extensions against hardware #7205 (comment) are fixed
