Add `enqueue_links` helper
We should provide a similar helper to what we have in crawlee.
https://crawlee.dev/api/core/function/enqueueLinks
In a nutshell, there is base implementation, which requires a list of URLs, filters them based on the provided options (e.g. globs/regexps or the enqueue strategies) and adds them to the RQ. Then we have contextual helpers in each crawler, e.g. CheerioCrawler has its own context-aware variant, which operates on the current page, and automatically finds all the links (matching the selector option, which defaults to just a).
The enqueuing strategies are described here:
https://crawlee.dev/api/core/enum/EnqueueStrategy
We should first come up with the basic support for autoscaling, and have a BasicCrawler and BeautifulsoupCrawler classes.
We could start with a simple variant that will only work with regexps, and add more features/options going forward.
