Type piracy in minimum, maximum, extrema & isnan

[yha]

These methods are pirated for StaticArray types:

julia> using StaticArrays
julia> v = SVector.([2,1,3],[1,2,3]);
julia> minimum(v)
2-element SArray{Tuple{2},Int64,1,2} with indices SOneTo(2):
 1
 2
julia> isnan(v[1])
ERROR: MethodError: no method matching isnan(::SArray{Tuple{2},Int64,1,2})
[...]
julia> using GeometryTypes
julia> minimum(v)
ERROR: DimensionMismatch("No precise constructor for SArray{Tuple{2},Int64,1,2} found. Length of input was 1.")
[...]
julia> isnan(v[1])
false

Looking at the code, it looks likes the new minimum is supposed to compute dimension-wise minimum but is failing.
I feel these minimum and isnan implementations are a bit questionable for points too. They don't really do what these functions are supposed to be doing. But they definitely shouldn't change the definition for StaticArrays.

GeometryTypes is deprecated...
GeometryBasics doesn't pirate minimum/maximum anymore...But still isnan ... I would mind restricting isnan to only work for GeometryBasic types ;)

Oh, I missed that deprecation.
I guess I'll try migrating my code to GeometryBasics, and open a PR there.
