Maybe NonEmpty types in a tuple do not generate the expected nullable / undefined values in corresponding Typescript list

[kallevmercury]

Type Example

data WidgetActionPayload
  = Activate (Maybe SparkLevel)
  | Reject Text [PromptKey]
  | Defer Text [PromptKey]
  | InfoRequest Text [PromptKey] (Maybe (NonEmpty ExtraInputPrompt))
  | UnknownResult Model.VoidData
  deriving stock (Show, Eq, Data)

Output Being Generated

contents: [string, string[], TExtraInputPrompt[]]

Expected Output

contents: [string, string[], TExtraInputPrompt[] | null]

or

contents: [string, string[], TExtraInputPrompt[] | undefined]

Testing

I tried to write a new test case for this to help replicate the issue (#48):

1) Generic instances TestMaybeTuple should handle Maybe in tuples correctly
       expected: [TSTypeAlternatives {
                   typeName = "IConWithMaybe",
                   typeGenericVariables = [],
                   alternativeTypes = ["[string, number[], string[]]"],
                   typeDoc = Nothing
                 }, TSTypeAlternatives {
                   typeName = "ISimpleConstructor",
                   typeGenericVariables = [],
                   alternativeTypes = ["string"],
                   typeDoc = Nothing
                 }, TSInterfaceDeclaration {
                   interfaceName = "IConWithMaybe",
                   interfaceGenericVariables = [],
                   interfaceMembers = [TSField {
                 @@ 4 lines omitted @@
                 }, TSField {
                   fieldOptional = False,

                   fieldType = "IConWithMaybe",
                   fieldDoc = Nothing
                 }],

                 @@ 21 lines omitted @@
                 
        but got: [TSInterfaceDeclaration {

Thanks for the report! Should be fixed now, let me know if you have any other problems.

@thomasjm Amazing! Thank you for such a fast response to this. I will try it out.
