The need to define a StructType for each parametric type

[yakir12]

I might be wrong but it seems like we need to define a StructType for each and every parameterized parametric type?

using JSON3
struct MyParametricType{T}
    t::T
    MyParametricType{T}(t) where {T} = new(t)
end
MyParametricType(t::T) where {T} = MyParametricType{T}(t)

x = MyParametricType(1)

JSON3.StructType(::Type{MyParametricType}) = JSON3.Struct()
str = JSON3.write(x) # ERROR: ArgumentError: MyParametricType{String,Int64} doesn't have a defined `JSON3.StructType`

JSON3.StructType(::Type{MyParametricType{Int}}) = JSON3.Struct()
str = JSON3.write(x) # fine
