Add a script to check for various inclusion criterias

[adriantombu]

As promised almost 3 months ago, here's a script that checks for the following criterias for the existing crates listed on the repo:

• The crate has at least 4k recent downloads on crates.io
• The package's repository is not archived

I also added back crates I previously removed by error and cleaned existing ones that did not meet the above criterias.

Please note that I am by no means any good in bash scripting so I did my very best here and probably spent too much time writing those lines.

As a future addition in another PR, we can add the check to the last criteria ("The package is not flagged as unmaintained in the Rust security advisory database") to clean some crates that have gone unmaintained for many years.

Thanks for taking the time!
Could we run it in CI, perhaps skipping the GitLab part, if it indeed requires a token?

[LukeMathWalker]

It doesn't look like we need auth for this? https://docs.gitlab.com/ee/api/projects.html#get-a-single-project

Unfortunately an authenticated call to the Gitlab API only returns a fraction of the project fields and archived is not part of it.

It's not well described in their doc, you juste have a brief explanation of it in https://docs.gitlab.com/ee/api/projects.html#list-all-projects where they talk about

When simple=true or the user is unauthenticated this returns something like:

Same here, we don't need a token for public repositories: https://docs.github.com/en/rest/repos/repos?apiVersion=2022-11-28#get-a-repository

Unfortunately we need it, there's a rate limit of 60 api calls for unauthenticated users https://docs.github.com/en/rest/using-the-rest-api/rate-limits-for-the-rest-api?apiVersion=2022-11-28#primary-rate-limit-for-unauthenticated-users
