Consider splitting out the create command

[jaredpalmer]

Current Behavior

tsdx create is just another cli command. However, it shares almost zero code with the other commands and in fact makes things harder for them since certain values like paths.js are all undefined.

Desired Behavior

Split out the creation script into a separate package or isolate the code so that it does not interfere or cause headaches throughout the rest of the codebase

Suggested Solution

• Make a separate create-ts-project package. Thanks to the create prefix, it will work with yarn create. So people will be able to enter yarn create ts-project (instead of using npx).
• Gluegun appears to have support for templating use .ejs, so that's worth evaluating during Use CLI Framework #17

Who does this impact? Who is this for?

Errbody.
