📖 If this PR requires documentation updates, I have created a separate PR (or issue, at least) in dvc.org and linked it here.I've significantly optimized LFS prefetching performance. With this change,
includeinscmrepo.git.lfs.fetch()is now a single-item list with either a Unix filename pattern like<subdir>/**or a file path.scmrepo.git.lfs.fetch._collect_objects()still enumerates all files in the repo withfs.find("/")(that's quite fast even with many files) butscmrepo.git.lfs.fetch._filter_paths()only matches those files against a single pattern.Partially fixes iterative/scmrepo#338.
