Parser to convert from .NET ticks

[supersime]

I am reading dates from a 'Microsoft'-based system that is storing dates as a .NET Tick. When I use these dates I need to convert them for use in JavaScript.

I'd like to see a parser method such as DateTime.fromTicks(ticks) to help convert this into a DateTime object.

I can use this instead, but it's a bit of a "magic number" and would be much easier to use if it was just built into Luxon:

DateTime.fromMillis((ticks - 621_355_968_000_000_000) / 10_000);

I'll defer to @diesieben07 because he runs things here now, but there are three reasons not to support this directly in Luxon:

1. As far as I know, it's not standard outside of .NET
2. having fromTicks would naturally lead users to think that Luxon supported nanosecond precision, which it doesn't. Principle of least surprise
3. It's pretty easy to add as a utility method. From the contributing guide: "Luxon shouldn't contain simple conveniences that bloat the library to save callers a couple lines of code. Write those lines in your own code."

Absolutely agreed with @icambron. There are a plethora of date formats out there and Luxon cannot add parsers for all of them.
