Indexing rows using `end` keyword errors

[kahaaga]

Describe the bug

Indexing a state space set with end keyword (e.g. x[1:end, 2:3]) errors. I'd expect this to work. Providing an explicit range (e.g. x[1:n, 2:3] does not error.

Minimal Working Example

julia> x = StateSpaceSet(rand(10, 2))
2-dimensional StateSpaceSet{Float64} with 10 points
 0.29452   0.423066
 0.461336  0.01487
 0.34901   0.568634
 0.225427  0.198393
 0.558053  0.901908
 0.101409  0.74085
 0.670569  0.656894
 0.384735  0.399064
 0.563578  0.54824
 0.176497  0.592265
