This PR: 1. Adds basic support for `CustomValue` to `explore`. Previously `open foo.db | explore` didn't really work, now we "materialize" the whole database to a `Value` before loading it 2. Adopts `anyhow` for error handling in `explore`. Previously we were kind of rolling our own version of `anyhow` by shoving all errors into a `std::io::Error`; I think this is much nicer. This was necessary because as part of 1), collecting input is now fallible... 3. Removes a lot of `explore`'s fancy command help system. - Previously each command (`:help`, `:try`, etc.) had a sophisticated help system with examples etc... but this was not very visible to users. You had to know to run `:help :try` or view a list of commands with `:help :` - As discussed previously, we eventually want to move to a less modal approach for `explore`, without the Vim-like commands. And so I don't think it's worth keeping this command help system around (it's intertwined with other stuff, and making these changes would have been harder if keeping it). 4. Rename the `--reverse` flag to `--tail`. The flag scrolls to the end of the data, which IMO is described better by "tail" 5. Does some renaming+commenting to clear up things I found difficult to understand when navigating the `explore` code I initially thought 1) would be just a few lines, and then this PR blew up into much more extensive changes 😅 ## Before The whole database was being displayed as a single Nuon/JSON line 🤔  ## After The database gets displayed like a record  ## Future work It is sort of annoying that we have to load a whole SQLite database into memory to make this work; it will be impractical for large databases. I'd like to explore improvements to `CustomValue` that can make this work more efficiently. |

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.
