package: Add autoload demo entrypoint

[shazow]

So people can do things like npx whatsabi --address 0xasdfasdf --rpc-url https://infura.alchemy

Most of the code already exists in examples/autoload.ts, just need to tweak the input and output handling.

2 brainstormy ideas

Record a gif automatically

When you make this you can automate making a gif of the cli pretty trivially using charmbracelet/vhs

Output ./examples/demo.gif
Type "npx whatsabi --address 0xasdfasdf --rpc-url"
# Pause for dramatic effect...
Sleep 50ms
Enter
Sleep 100ms

compose with cast

A use case people might like is using this whatsabi cli to pipe a result into a cast command?

Good ideas!
