[BUG]: custom values using jsonTypeBoolean become "true"/"false" instead of true/false

[julianvv]

When I tried to add a custom boolean value inside my JWT I stumbled upon this issue. My JWT wasn't parsed correctly by some other libraries on a client application. Turned out that the value was passed as a string to the l8w8jwt2(64).dll because in the EncodeJWTEx function GetMemberValue gets used. The GetMemberValue function always returns a string. That's why I created a fix that I will try to open a pull request for. The fix is as follows:

Get MemberValue of hoJsonWebToken sMemberName to sMemberValue
Get MemberJsonType of hoJsonWebToken sMemberName to iJsontype // This needs to be called earlier than before (above the allocate memory for the value string)

// Change boolean value from 1/0 to true/false
If (iJsontype = jsonTypeBoolean) Begin
   If (sMemberValue) Begin
       Move "true" to sMemberValue
   End 
   Else Begin
      Move "false" to sMemberValue 
   End
End
