This implements the suggestion in #1248.

After this,

julia> S = Symmetric(rand(3,3))
3×3 Symmetric{Float64, Matrix{Float64}}:
 0.376244  0.895193  0.332219
 0.895193  0.563134  0.148036
 0.332219  0.148036  0.711689

julia> vals = eigvals(S)
3-element Vector{Float64}:
 -0.45018177966363415
  0.5911683834592292
  1.5100812026842658

julia> eigvecs(S, vals[1:2])
3×2 Matrix{Float64}:
  0.752343  -0.16258
 -0.645224  -0.37737
 -0.132912   0.911679
