Cleanup temporary files on process.exit event.

[akshitsinha]

Can there be an option to .file() and .directory() which cleans up files/directories on process.exit?

Example:
tempy.directory({ cleanup: true })

I've tried using tempy.file.task() but Jest ignores tests enclosed in any external function.
Example:

describe("Sample test", () => {
    tempy.file.task(tempFile => {

        // Both these tests dont get executed by Jest
        it("Sample 1", () => {
            expect(true).toBeTruthy() // Wanted to use the file in here.
        })
    
        it("Sample 2", () => {
            expect(true).toBeTruthy() // And the same file here again.
        })
    })
})

I can create a file/directory externally outside and then delete it myself, but that would be tedious. Temporary files on Windows don't get deleted automatically unlike on MacOS, so an option to cleanup on node process exit would be pretty convenient.

The problem is that there's no reliable way to detect if a process is exiting. process.exit misses a lot of cases. See: nodejs/tooling#42

If {cleanup: true} option is passed maybe create file in temporary directories (/tmp for linux and %localappdata%\Temp for windows). For windows system, files may be not deleted automatically but wont be a task for manual deletion for the user.
What are your thoughts?
