Ship a CLI for visualizing a run in terminal

A crate with very basic functionality in-terminal animation capabilities for Lattice2d. 

Example of what a command might look like.

```bash
ising --width 500 --height 200 --beta 0.5 --nruns 10000 --flipsperrun 10000 --j 1.0
```

With a `--verbose` option for printing metadata about the runs, i.e. magnetization, energy, susceptibility etc.
