Stack overflow when broadcasting results in StaticInt eltype

Found this...

julia> import ArrayInterface: StaticInt

julia> r = StaticInt(1):4
StaticInt{1}():StaticInt{1}():4

julia> broadcast(-, r, StaticInt(1))
ERROR: StackOverflowError:
Stacktrace:
 [1] UnitRange{StaticInt{0}}(::StaticInt{0}, ::StaticInt{3}) at /Users/zchristensen/.julia/packages/ArrayInterface/NbkVT/src/static.jl:108 (repeats 79984 times)

...and traced the issue back to Base._range assuming that UnitRange should be formed with an element type that is a StaticInt.

The easiest way to fix this would be our own Base._range(::StaticInt, ...), but I'm not sure if that's a good entry point since it's not public API.

Edit:
also found this

julia> (StaticInt(1):10)[1:2:6]
ERROR: MethodError: no method matching StepRange{StaticInt{1},Int64}(::StaticInt{1}, ::Int64, ::StaticInt{5})
Closest candidates are:

Inizia riproducendo entrambi gli esempi in Julia, poi esamina src/static.jl:108 e base/range.jl di Julia intorno a Base._range e alle righe 107-118. Traccia come vengono costruiti gli intervalli StaticInt e come lo slicing raggiunge StepRange; il lavoro è completato quando il broadcasting non va più in overflow e l'espressione di intervallo con passo mostrata non solleva più il MethodError riportato.
