Remote fetching

[Sk7Str1p3]

Summary 💡

Print some info about repository without pulling it locally.

Motivation 🔦

Some repositories are enormous, and people may want know just few essentials like name, authors, LoC and size without cloning it. So IMO this could be great feature

Even if onefetch was updated to be able to run on bare repositories, it would still need to clone the repository to read it (but we could possibly skip resolving deltas).

AFAIK, the only way to truly avoid cloning a large repository would be to rely on the host's API. So that would require defining a second way to fetch all the stats, some of which might not be available. Additionally, we'd need to be able to read from the GitHub API, GitLab, and other major hosts, unless we're going to show favoritism for one git host.
