Ticket1843: Nanodac Support

[DominicOram]

Description of work

Added the nanodac IOC.

To test

You will also need https://github.com/ISISComputingGroup/EPICS-nanodac

Fixes ISISComputingGroup/IBEX#1843

Add the nanodac as part of a configuration. It is currently on 130.246.49.95.
Check that you can read all four channels on %MYPVPREFIX%NANODAC:CH1:PV etc. PVs should be around room temperature.

Code Review

• Is the code of an acceptable quality?
• Are the PVs named according to the naming standards.
• Have suitable disable records been added?
• Have suitable simulation records been added?
• Have the finishing touches been applied?
• Is there an emulator for the device?
• Have the changes been documented in the release notes. If so, do they describe the changes appropriately?
• If an OPI has been modified, does it conform to the style guidelines? There is a script called check_opi_format.py to help with this.

Functional Tests

• Do changes function as described? Add comments below that describe the tests performed.
• Does the IOC respond correctly both in full and simulation mode, where it's possible to test both?
• If there are multiple _0n IOCs, do they run correctly?

Final steps

• Reviewer has updated the submodule in the main EPICS repo? See Reviewing work for the subModules of EPICS in the Git workflow page for details.
• Reviewer has moved the release notes entry for this ticket in the "Changes merged into master" section

Have fixed the issues highlighted via slack

[DominicOram]

Fixed the follwoing issues highlighted on Slack:

• Changed name to NANODAC-IOC-01
• Added SIM/DISABLE
• Changed PV names to be more understandable (so now look at %MYPVPREFIX%NANODAC_01:CH1:TEMP)

Note that some of these changes are in the support module, you will need the latest master from that repo.
