Avoiding type piracy in `kron`

[jishnub]

https://github.com/JuliaMatrices/LazyBandedMatrices.jl/blob/d0fa057258960095c074dd9cd09c32f7ca2077d2/src/LazyBandedMatrices.jl#L159-L169

Since this is type-piracy, I wonder if it might not be better to define a kron function inherent to this module instead of overloading the one from LinearAlgebra?

It would actually be better to move this kron implementation to BandedMatrices.jl.
