Export resolve paths as function

[Bielik20]

This is my proposal to add option to use this package in code through standard import without damaging existing functionality.

Why?

I wanted to use this in rollup as a plugin so I needed a way to import function and execute it. Plugin looks like that:

import { resolvePaths } from 'tscpaths'

function tscpaths() {
  return {
    onwrite() {
      resolvePaths({
        project: 'tsconfig.json',
        src: './src',
        out: './dist/types'
      })
    }
  }
}

Misc

I have updated globby becuase it has now its own types so @types/globby is no longer necessary.

@Bielik20 Hey thanks for PR, but since you split the original file into two different files. It's really hard to review what has changed.

[Bielik20]

@joonhocho You are right I should have written summary. I did not touch the logic at all I simply put it in the functions (resolvePaths and command). I have changed paths to "main", "module" and "types" to point to newly created function resolvePaths. Also "bin" now points to to the cjs/run.js where the command function is executed.

Should you require more in depth explanation let me know.

@joonhocho Is there something you require of me?
