Cut `banana` out of `ekobox`

[alecandido]

Maybe the solution is just a forth package, ekobox and ekomark will depend on it, but at least ekobox won't depend on ekomark, and we're sure will not depend on banana.

@scarlehoff we were thinking about this as a solution for the problems in NNPDF/nnpdf#1529

This is in the milestone for 0.9.4 (which has been reelased) but it is not closed. What is the status? (to know whether I have to update the conda recipe or not: conda-forge/eko-feedstock#3)

[alecandido]

The person that released v0.9.4 simply forgot to update the milestone (milestones in EKO have been just introduced, people are not familiar with them...). I'm updating it.
