This commit introduces new collectors for npm, cargo, and go modules, allowing users to archive package metadata and source code from their respective registries.
The `npm` and `go` collectors have been fully implemented, with commands and unit tests. The `cargo` collector is also fully implemented, after a period of being blocked by the `crates.io` API. The correct `User-Agent` was found by inspecting the `cargo` binary.
The `pypi` collector has not yet been implemented, but a clear path forward has been established by successfully fetching package metadata from the `pypi.org` API.
This commit also addresses feedback from a previous code review, including the removal of a `tcpdump.log` file and the correction of several nitpicks.
