• lint tests ok (reached Wrote Zip to disk)
• unit tests passed (Tests completed in 512 milliseconds. 566 assertions of 566 passed, 0 failed.)
• added name to package.json and readme.md

Been a long time user (and fan) of the plugin, hope to start contributing by adding parsers for the sites I visit.

I hate to tell you this, considering the effort you put in, but the site https://novelnext.com/ is just another alias for https://allnovelnext.com/. So, you didn't need to write a new parser, you just needed to register another hostname to the NovelfullParser. See: https://github.com/dteviot/WebToEpub/blob/ExperimentalTabMode/plugin/js/parsers/NovelfullParser.js#L3-L35
As I'd love to give you credit for your work, if you like to amend your commit, I'll be happy to accept.

Note,

1. You might like to add https://novelnext.net/ as another alias as well.
2. Please add in alphabetical order, it makes it easier to check if an alias has already been added.

Firstly, thank you very much for your contribution. It's aways a happy occasion to have another contributor.
Second, I apologize for not being clearer in my previous comment. You did not need to include the NovelNextParser.js file, just registering another hostname would have been sufficient.
However, it's not a problem. I've deleted the unneeded file.
