Transceiver by version

[Christian-B]

Preparation work for Different Transceivers by Version.

There is an AbstractTransciever Which is just an API
A BaseTransceiver which holds the shared coded
There is highly likely going to be another Spin1/spin2 layer between base and specific
Then Version3 and Version5 Transceivers.

There is also a MockableTrableTransceiver to Extend in Unittets

There is also Extended Classes so that the ExtendedTranceiver can be any version

The selection of which Transceiver to use is done by methods in tranceiver_factory.

Must be done at the same time as:
SpiNNakerManchester/SpiNNFrontEndCommon#1099
SpiNNakerManchester/sPyNNaker#1376

Tested by:
SpiNNakerManchester/IntegrationTests#224

Looking good in principle, but I'm on my phone so I can't be more thorough than that for now. 😁

I'd be tempted to call the abstract class just Transceiver to minimise the amount of fixing up of comments (and type annotations on my branches) as there really aren't very many places that make transceivers but an awful lot more that use them.

That makes a lot of sense and one I wondered about.
I intentional did not while working on it to be sure to change all places used in code.
