Give a hand to downstream packages to update to v0.22

[Kolaru]

Many packages depending on IntervalArithmetic have not been able to update themselves to the newest version.

I think it would be great if we put some effort helping others, once the packages in JuliaIntervals are updated themselves.

In particular, all of the JuliaReach ecosystem is lagging behind, see e.g. JuliaReach/RangeEnclosures.jl#181
