✨ Let the user choose which file to download in a folder

[o-laurent]

Hello,

I'm building a library with datasets hosted on Google Drive, but I have some annoying specifics.

I would like to download a certain number of files with known names given the Google Drive ID of their folder. Please note that I don't have the ID of the files themselves. To be precise, the idea is that allowed users get the link to the folder, but I want to spare them the need to get and report each of the file IDs to start the download of the dataset. This could look like an optional filename in the folder download API.

I can give you a hand in crafting some prototypes in a PR if you think that it is relevant to the library.

Thanks in advance!

@o-laurent Sounds useful. Maybe we can pass multiple regex patterns like .gitignore?

My one concern is that the download_folder only can scan 50 files due to the limitation of shared folder on gdrive. We probably should raise error if --remaining-ok is not provided.

Other than that, I think it makes sense to have this feature on Gdown.

Thanks @wkentaro for your advice, I have suggested the following PR #310.
