Explicit typecast in `pcasvd` prevents FixedSizeArray usage

[bertini97]

Hi, when using FixedSizeArrays and trying to do PCA with the SVD method

using FixedSizeArrays, MultivariateStats
M = FixedSizeArray(randn(10, 100))
fit(PCA, M, method=:svd)

one is met with

TypeError: in typeassert, expected Vector{Float64}, got a value of type FixedSizeArray{Float64, 1, Memory{Float64}}

Stacktrace:
 [1] pcasvd(Z::FixedSizeArray{…}, mean::FixedSizeArray{…}, n::Int64; maxoutdim::Int64, pratio::Float64)
   @ MultivariateStats ~/.julia/packages/MultivariateStats/sSKHh/src/pca.jl:242

because of the cast in

MultivariateStats.jl/src/pca.jl

Line 242 in 1c26eff

v = Svd.S::Vector{T}

Overwriting the function removing the explicit typecast makes it work (it results in an unrelated error in StatsBase). Is there something that can be done about this? Thank you in advance.
