readline support

[andyDoucette]

It would be a nice addition if askai live prompt used gnu readline so we we can use the shortcuts we've gotten used to at the prompt. For example:

• Ctrl-Left to go back a word.
• Ctrl-K to cut things to the right of the cursor
• Ctrl-W to cut a single word and add it to the buffer.
• Ctrl-Y to paste the buffer

It's helpful when you want to edit a word 4 words ago. Ctrl-w-w-w, edit, Ctrl-y and it's done.

Looks like there's a node package for this too: https://nodejs.org/api/readline.html

@andyDoucette that's a great suggestion. I will work on it as soon as I can find some time for it
