Recursive mkdir to allow path.sep in a path

[justinormont]

From #43:

Prefix which includes a path.sep fails.

Repro

This fails as the path will include a path.sep:

const uuid = 'xyz';
const prefixForRun = path.join('runs', `run_${uuid}`);
const outputFolder = temporaryDirectory({prefix: prefixForRun});

This call results in a path of:
'/private/var/folders/6t/frtzt7q96fv9xjqp3knl3vqh0000gn/T/runs/run_xyz'

The mkdir for run_xyz fails since the parent, /private/var/folders/6t/frtzt7q96fv9xjqp3knl3vqh0000gn/T/runs/, does not exist.

Error

Error: ENOENT: no such file or directory, mkdir '/private/var/folders/6t/frtzt7q96fv9xjqp3knl3vqh0000gn/T/runs/run_xyz'
    at Object.mkdirSync (node:fs:1324:3)

Solution

In mkdir, add the {recursive: true} option.

Discussion

Incidentally, fixing this gives an indirect method of #35, as my intention was similar. To organize my temp files/folders for later cleanup, I was adding a parent folder to my requested temp folder.

Closes #43

@sindresorhus: Can you take a look at my short PR?

[sindresorhus]

Better to put this into a separate test.

Use t.is

I don't think this is a good idea. What if you want just a parent directory and not a name prefix. That becomes awkward. I think it would be better to introduce a new option that worked for both file and directory called parentDirectory.

Closing for lack of activity.
