Add support for `npx tsdx create .`

[Johannes Skuterud]

Current Behavior

If I have an existing project folder or repository, I first run npx tsdx create foo, then copy the contents of foo to the root of my project.

Desired Behavior

First cd into an existing project folder, then run npx tsdx create . This should then setup all files and folders in the root of the project folder.

Suggested Solution

I suggest using a similar implementation as npx create-next-app . or npx create-react-app .
