Feature: CLI invocation

[Vandivier]

I have deno installed within a Ubuntu session on Windows using WLS2.

Basically, my VS Code doesn't have access to Deno.

I would like to be able to cd to the folder of my choice and run a CLI command instead of using deno init VS Code command.

@Vandivier this is a valid usecase but may not be the scope of the extension. I may probably create a CLI tool for this
