Copying into a folder doesn't work without specifying a filename in destination

[kayvanbree]

On Windows, the following command works:

cp-cli README.md dist/my-lib/README.md

But the following commands don't work:

cp-cli README.md dist/my-lib/
cp-cli README.md dist/my-lib

According the docs the first one (with the slash) should work, but instead it gives the following error:

{ [Error: EPERM: operation not permitted, unlink 'C:\Projects\my-project\dist\my-lib']
  errno: -4048,
  code: 'EPERM',
  syscall: 'unlink',
  path:
   'C:\\Projects\\my-project\\dist\\my-lib' }

I solved this by adding the filename, but wanted to let you know. I don't know if this is also a problem on Unix systems.

Great work on this library by the way! cpx didn't want to copy a folder with assets and it hadn't been released for 3 years, so it's nice to see a fresh new copy library.

I created a test environment for Windows here 3ee0afa and try to reproduce and fix it ☺️
Thank you for the report and feedback 👍

After looking around I found out that in the last couple of years a lot of new, and better, alternatives to cp-cli were created. So in favour of cpy-cli, ncp and cpx I will archive this repository.
