How to get Real64 from MC Protocol

Request:

I think i might have fixed REAL value support however I currently have no means of testing.

If you are in a position to help I would appreciate it.

To test this branch, could you install and test out?

In your .node-red directory, run:

npm install https://github.com/Steve-Mcl/node-red-contrib-mcprotocol#add-real-double

Let me know if that works
