Create new Ink app in a new directory

[kevin940726]

Close #1.

Added support to pass a new input <project-directory> indicating where the project should be scaffolded in. Currently the input is optional, the current directory will be the default if it's not present, so that we can make this feature backward-compatible. In the future, we should at least add a warning if the input is not passed.

I also added some basic helpful message upon successfully created an app. Wordings are TBD.

Example:

create-ink-app # Create an Ink app in the current working directory
create-ink-app . # Same as above
create-ink-app my-cli # Create an Ink app in the "my-cli" directory relative to the current working directory
create-ink-app --typescript my-cli # Typescript template also works

I intentionally move some logic to cli.js so that in the future we can support programmatic API by directly importing index.js as well.

What do you think of a --template flag like in create-react-app?

It would be interesting if the value received in the template argument matches the name of the template folder in the templates directory of this project ->

Example:

npx create-ink-app my-fancy-ts-cli --template typescript-eslint

The templates folder

# ...
templates
 |- _common
 |- js
 |- ts # rename to "typescript"
 |- typescript-eslint
   |- # ...
   |- tsconfig.json
   |- .eslintrc
   |- # ...
# ...

I didn't test anything. I left 1 suggestion. I didn't notice anything concerning that should prevent merging.

I would recommend making "project-directory" a flag too. It seems safer than accessing it as index 0.

cli.input[0] seems fragile if for some reason something is misaligned and at position cli.input[1] instead.

[mattferrin]

(I don't feel strongly about this.)

[mattferrin]

I retract my suggestion. Convenience is more important. (I like the way you have it.)
