Idea: SCPI refactor

[cyr123]

Background:

I have about 20 programmable instruments on my bench, only about half are SCPI-compliant but most of the rest support IEEE 488.2 "star" commands.

I suggest moving the commands defined by 488.2 from SCPIInstrument into a new class (IEEE4882Instrument?) which will be the new base class for SCPIInstrument. I'd also like to move everything else that isn't actually defined as required in the SCPI standard somewhere else.

I'll probably do this for my own use in any case, but I'd prefer if it could be upstreamed, so comments?

Can you give me an example of what has been implemented in SCPIInstrument but not supported by these half-support instruments?
