You asked in our discussion for opening an issue: very cool and promising. thanks for your great work! would it be possible to deliver dynamic [Franklin](https://github.com/tlienart/Franklin.jl) projects? As discussed, I...

map(f,::DNDSparse) fix for changing value type

1

fixes failing ```julia filter(isodd, map(v->v.a+1,ndsparse((numid=1:10,), (a=1:10,b=1:10); chunks=2))) ```

I required to append to `JuliaDB.DNDSparse`, similar to other users (https://discourse.julialang.org/t/append-rows-to-a-juliadb-table-on-disk/44071). To achieve this, I refactored code regarding `fromchunks`, `vcat` chunks and `serialize` the index out of `function _loadtable` into...

map(f,x::DNDSparse) produces wrong parametric type if f changes value type

```julia A = ndsparse((numid=1:10,), (a=1:10,b=1:10); chunks=2) B = map(v->v.a+1,A) ``` seems to work, but assigns wrong type parameter `typeof(B)` ``` JuliaDB.DNDSparse{NamedTuple{(:numid,),Tuple{Int64}},NamedTuple{(:a, :b),Tuple{Int64,Int64}}} ``` which makes ```julia C = filter(isodd, B)...

issue #30 pointed to possibly - refactor result_type to dynamic computation (not at construction time), - retain the option to assert a result_type with a WrappedParser. `TextParse.AbstractToken{T}` compatibility required representing...
