fix: 🐛 Parse old aspnet dates instead of unreliable format strings (#108)

Parse old asp.net dates instead of string

Parsing with DateTime.fromFormat are not 100% sure on all devices -
for me I got undefined in iOS simulator but it worked fine in Node.
( see https://moment.github.io/luxon/docs/manual/parsing.html#fromformat)

✅ Closes: #105
