Add option to suppress error when directory exists

[iFwu]

Description

There're some situations that I want to scrape multiple organized pages to one directory, but it will throw an error. So, is possible to add an option to suppress the error when directory exists(though I can delete the code of throwing error)? PS: The reason why I don't use [url1, url2, ...] in urls option is that I want fully control of the scrapping process, like use 'promise-limit' to limit the concurrency and resume scraping after break.

You can use resourceSaver option to overwrite default behavior and save to existing directory.

But be aware that saving to existing directory may include next tricky things:

• resolving conflicts between generated filenames and existing files
• handle corner cases like different access rights to files and directories, symlinks, etc.
