Feature request: Support for passing multiple --archive-file args

[ranger-ross]

Motivation

I have a large workspace that has a bunch of platform specific crates and for various reasons we have to run cargo nextest run multiple times with different configurations.

This works but i'd be nice if I could do these builds all up front and have all of the tests run together so the output accounts for all of the tests combined.

Proposal

cargo nextest archive exists and I think that would work if cargo nextest run allowed multiple --archive-file args to be passed.

cargo nextest run --archive-file my-first-test-set.tar.zst --archive-file my-second-test-set.tar.zst

Running this command would run all of the tests for both archives and combine their test ouputs (like the stderr output, junit report, etc)

I don't know much about nextest's internals so not sure if this is feasible.

Alternatives

Admittedly, our workspace is not what I'd call a shining example, so if the response is "fix your workspace and use the existing nextest filtersets" that is fair 😅
Though I think this could be useful for scenario where people want to build different parts of the test suite on multiple machines

Additional context

No response

Thanks for the feature request. I think this would be quite difficult to explain to ordinary users, in particular what happens if e.g. two archives have the same test name? What happens if the corresponding metadata is different? Etc.
