No method matching setindex!(::fmpz_mat, ::fmpz, ::Int64)

[albinahlback]

julia> b = fmpz_mat(1, 3)
[0   0   0]

julia> b[2] = ZZ(2)
ERROR: MethodError: no method matching setindex!(::fmpz_mat, ::fmpz, ::Int64)

However, we have

julia> b[2]
0

I suppose it's similar for other structs.

The main reason we haven't provided setindex! is that Julia is column major, whereas Flint is row major. This cause general could in confusion.

However, we could support it for vectors only, now that this seems to be a thing in Nemo.
