Full-rank SVD has high error

I am not exactly sure if this is correct, but I would expect the result to be close to zero. ```julia using TSVD, LinearAlgebra A = randn(10, 10) U, S,...

Hey there, would it be possible to support arbitrary types? As it stands this doesn't work: ```julia-repl julia> using TSVD julia> using DoubleFloats julia> a = rand(Double64, 4, 5) 4×5...

a problem with TSVD.teig - anything I did wrong?
