Is there a way to download a specific DLC installer file?

--download-file gamename/fileid
works when the fileid is numerical, but for installers that is not the case.
For example, fileid "en1installer0" can be the base game installer and one or more DLC installers at the same time.

Maybe this syntax should be supported?
base_gamename/dlc_gamename/fileid

Like:
the_witcher_3_wild_hunt_game/dlc_16_a/en1installer0

(Also, why does gamename in --download-file is parsed as regex? Kind of annoying and seems a little bit useless. Having different switches for normal and regex modes would be better I think. --download, --download-regex, --download-file, --download-file-regex)

761c3f1 Improvements to --download-file option

Allows downloading DLC files by extending file selection.
Files can be selected by using the name of dlc
--download-file "gamename/dlc_gamename/fileid"

It used regex because it uses the same code as --download and --galaxy-install to get game names and product ids.
This commit makes the downloader use exact match.
Well not really an exact match but kind of by automatically adding "^" prefix and "$" suffix to the regex in Downloader::downloadFileWithId

Wow, thanks for the quick addition. It works.

Thanks!
