* Fix drop nth bug on ranges. Should fix & close #5260

* Fix drop nth bug on ranges. Should fix & close #5260

* Add support for ranges

* Working version of drop nth, but the issue is that we unwrap the value which is problematic for Streams. Should convert to the way @stormasm was doing it before and implement the range check

* Fix fmt issue

* Drop nth now works for Lists, Records, and Ranges. We need support for ListStreams and for ExternalStreams

* Keep consistent naming

* Fix fmt issue

* Support ListStreams for drop nth

* Use DropNthIterator instead

* Found a more elegant way to deal with the check for no upper bound input

* Add extra checks for negative inputs or to < from for ranges

Nushell core libraries and plugins

These sub-crates form both the foundation for Nu and a set of plugins which extend Nu with additional functionality.

Foundational libraries are split into two kinds of crates:

  • Core crates - those crates that work together to build the Nushell language engine
  • Support crates - a set of crates that support the engine with additional features like JSON support, ANSI support, and more.

Plugins are likewise also split into two types:

  • Core plugins - plugins that provide part of the default experience of Nu, including access to the system properties, processes, and web-connectivity features.
  • Extra plugins - these plugins run a wide range of different capabilities like working with different file types, charting, viewing binary data, and more.
