ElasticArrays input broken for arrows

[chakravala]

Makie v0.21.18

using ElasticArrays
arrows(ElasticArray(zeros(Point{3},10)),ElasticArray(zeros(Point{3},10)))

ERROR: MethodError: Cannot `convert` an object of type 
  ElasticVector{Vec{3, Float32}, Vector{Vec{3, Float32}}} to an object of type 
  Union{Vec3f, Vector{Vec{3, Float32}}, GeometryBasics.Vecf{3}, Vec3{Float32}}

[chakravala]

one possible fix to this is to simply call vec on the inputs

Should be easy to fix by adjusting these methods:

Makie.jl/src/basic_recipes/arrows.jl

Lines 74 to 82 in 58fc475

	function convert_arguments(::Type{<: Arrows}, x, y, u, v)
	return (Point2{float_type(x, y)}.(x, y), Vec2{float_type(u, v)}.(u, v))
	end
	function convert_arguments(::Type{<: Arrows}, x::AbstractVector, y::AbstractVector, u::AbstractMatrix, v::AbstractMatrix)
	return (vec(Point2{float_type(x, y)}.(x, y')), vec(Vec2{float_type(u, v)}.(u, v)))
	end
	function convert_arguments(::Type{<: Arrows}, x, y, z, u, v, w)
	return (Point3{float_type(x, y, z)}.(x, y, z), Vec3{float_type(u, v, w)}.(u, v, w))
	end

These can probably rely on convert_arguments(PointBased(), x, y[, z]) to avoid duplicating code.
