Remove CICERO-SCM binary

[znicholls]

We shouldn't be packaging the CICERO-SCM binary here. We should update the model so it stores its version internally (i.e. the version can be queried by openscm-runner) and then we can remove the binary from being packaged here.

This is probably very dumb, but how do you suggest we send the package otherwise? If we are keeping the fortran version of ciceroscm around, the binary isn't publicly available anywhere else...

One way could be to archive the Fortran binary on Zenodo and then either

• make the wrapper automatically download the binary from Zenodo (e.g. using Pooch) if it doesn't exist locally, or
• instruct users to download it themselves and set a path somewhere (I believe this is what Pymagicc offered for MAGICC7)

Another option could be to have a small CICERO-SCM 'binary' package which could be imported by openscm

Ok, thanks, @rgieseke, I guess we might need to discuss internally what we'd prefer, and possible how far into the future we'd want to keep the fortran version up to date with things...
