Date Vector with missing entries

[kafisatz]

I run into the issue below with missing Date entries. Is this expected on JDF v0.4.0 ?

julia> col = [Date(1999,1,1),missing,today()]
3-element Array{Union{Missing, Date},1}:
 1999-01-01
 missing
 2021-04-14

julia> df = DataFrame(d = col)
3×1 DataFrame
 Row │ d
     │ Date?      
─────┼────────────
   1 │ 1999-01-01
   2 │ missing    
   3 │ 2021-04-14

julia> JDF.save(raw"c:\temp\fifi", df)
