An ISBN parsing library

# Usage

```csharp

if (ISBN.TryParse("9780753557525", out var isbn))

{

    Console.WriteLine($"Publisher: {isbn.Publisher}, Article: {isbn.Article} (Group {isbn.Group}, {isbn.GroupName})");    

}

> Publisher: 7535, Article: 5752 (Group 0, English language)

```

## Attribution

The implementation is mostly a port from https://github.com/inventaire/isbn3, and consumes the 

group information published in that repository.

[ISBN groups and ranges data](https://github.com/devlooped/isbn/blob/main/src/ISBN/groups.js) 

is kept up to date via [dotnet-file sync](https://github.com/devlooped/dotnet-file) from the 

isbn3 repository which in turn fetches [isbn-international.org](https://www.isbn-international.org) data.
