* Remove TCP server feature; this area is better served by the
CyberChef-server project
* Increase required version of commander to one which provides
`requiredOption()`
* Print the error message that is captured when failing to parse the
command line
Also use `fs.readFileSync()` to read the recipe file.
This fairly simple script leverages the Node API provided by CyberChef
to allow performing operations on local filesystem objects without
needing to copy them into and out of a browser window.
It requires a recipe to be specified at runtime as a JSON file.
Also includes a simple TCP server for use by other local processes. This
server is hard-coded to use localhost in order to discourage production
use of the script.
