Support specification of version using semantic versioning or other custom scheme

[elipousson]

Could the "version" component of a pin be expanded to add support for semantic versioning or other structured versioning schemes for datasets?

The desc:::idesc_bump_version() function is what handles this for {usethis} and a similar approach could be used here: https://github.com/r-lib/desc/blob/main/R/version.R

I definitely understand if this is out of scope but I figured I'd share the idea regardless.

Thanks for sharing this feature request idea! 🙌 Let's use this issue to gather feedback/interest on this particular idea. Somewhat related to #827 which is also about an alternative versioning scheme.
