Add web and desktop tags to pub.dev

[MichealReed]

This library does not have any native dependencies and can be used across all platforms. Adding the web and desktop tags may help with exposure of this great library. Thanks for building this!

Wow! I am so happy, I checked the repository out, and found this issue before not even trying to use the package! Definitely add the tags, sad to see many heads turn away for no good reason.

I am guessing it might be the fromCSV method? There are hacky ways to import csv files even when using web.

The following line can be used to import CSV files:

utf8.decode(<csv in byte object>);

You can use a parser like parseCSV from the grizzly_io package if you want to convert the string to list of lists - aka list of rows.

Full implementation.
