LeetCode interactive library and tooling

This is a set of a library for interacting with LeetCode through the lc_lib crate.

This provides bindings that lc_cli and lc_tui then use to allow a user to interact with LeetCode in a few different ways.

CLI

This is the primary way to interact with the library. This gives a way to use a simple CLI interface to get questions, solve them, and then submit them from the terminal.

TUI

This is the secondary way to interact with the library. This gives a front end within a terminal that mimics a GUI and gives a more interactive approach to solving and reading about the problems that LeetCode has to solve.
