Add a Lisp Script Seed

[mkasberg]

Add a Lisp "seed" script to the seeds folder. Basically, this would be an executable Lisp file (with #!/usr/bin/env sbcl --script or similar) that parses some simple command-line arguments (like -h or -t, see other scripts as examples) and prints a sentence or two to the command line. It's intended to demonstrate how to parse command line arguments and print something to the console in Lisp.

As a rough example, see #26.

E.x. Install sbcl with apt-get in the Dockerfile and use this script as a starting point:

#!/usr/bin/env -S sbcl --script

(write-line "Hello, world!")
