Version Restriction for IntervalArithmetic.jl Causing Problems

Currently LazySets.jl is restricting me from upgrading IntervalArithmetic.jl

```
⌅ [d1acc4aa] IntervalArithmetic v0.21.2 (<v0.22.21): LazySets
```
which is causing an error in my code:

https://github.com/JuliaIntervals/IntervalArithmetic.jl/issues/693

Can this restriction be removed?
