Issue with TSVD.jl in the Singular Case Compared to PROPACK.jl

[MohamedLaghdafHABIBOULLAH]

In the singular case, TSVD.jl appears to produce an error, while PROPACK.jl provides the expected results.
I’m wondering if this issue is something that could be easily addressed.

julia> using TSVD, PROPACK

julia> Bk = [202.0 0.0; 0.0 0.0]
2×2 Matrix{Float64}:
 202.0  0.0
   0.0  0.0

julia> PROPACK.tsvd(Bk;k=1)[2]
1-element Vector{Float64}:
 202.0

julia> TSVD.tsvd(Bk,1)[2]
