Enhancement request: treat files that begin "patch_" differently from files that begin "setup_"

[CalAlaera]

GOG doesn't seem to provide a useful way to discriminate between patches (e.g. patch_baldurs_gate_3_whatever_(66683).exe) and full game installers (e.g. setup_baldurs_gate_3_whatever_(67171).exe).

It would be great if gogrepo could process what the file name will be, and be configured to act differently depending on whether it matches one of these patterns. For example, if I simply wish to keep an archive of offline installers, I could configure gogrepo to only download files that begin with "setup_".

PR #60 does what you want. My fork includes this functionality, as well as a couple of other enhancements.
