[ENHANCEMENT] `Base.map!` needs refactor

[ogauthe]

#src/blocksparsearrayinterface/map.jl
@interface interface::AbstractBlockSparseArrayInterface function Base.map!(
  f, a_dest::AbstractArray, a_srcs::AbstractArray...
)

Base.map! is not compatible with the design of KroneckerMatrix.

• line 27, indexing a SparseArraysBase.SparseMatrixDOK{KroneckerMatrix fails as it tries to call Base.similar(::Type{KroneckerMatrix{...}}, dims::Tuple{Int,Int}) which cannot be defined (there is not enough information in type + size to init a KroneckerMatrix).
• line 39, it calls iszero on a SubArray{Float64, 2, KroneckerMatrix}. iszero is defined for a KroneckerMatrix, but the wrapper type prevents the dispatch and the fall back option errors on getindex
