Reverse Jacobian on StaticArrays

[gdalle]

Apparently reverse-mode jacobian tries to mutate something, and StaticArrays aren't happy:

julia> import Enzyme

julia> using StaticArrays

julia> x = @SVector(ones(2))
2-element SVector{2, Float64} with indices SOneTo(2):
 1.0
 1.0

julia> Enzyme.jacobian(Enzyme.Reverse, identity, x)
ERROR: setindex!(::SVector{2, Float64}, value, ::Int) is not defined.
 Hint: Use `MArray` or `SizedArray` to create a mutable static array
