[DRAFT - feedback needed] Sync crate and R package versions

[JosiahParry]

This PR closes https://github.com/extendr/rextendr/issues/304 and is related to #228.

This draft creates two functions use_version() and sync_version().

• sync_version() will set the version of the Rust crate in src to match that in the DESCRIPTION file.
• use_version() wraps usethis::use_version() and 1. calls usethis::use_version() to increment the package version and 2. syncs the version with sync_version()

I personally think masking functions from usethis is a little questionable. I like the workflow of:

• make some significant changes to a package
• usethis::use_version()
• sync_version()

Alternatively, we could change the name of use_version() to increment_version() to avoid namespace conflicts.

CC @eitsupi I would like your eyes on this! I opted for cargo-bump since it is easier to use and isn't tied to actually publishing a crate.

cargo-bump does not seem to be currently maintained and is not recommended to be used.

Sure, thats fine. More importantly, though, is the user experience. Do you prefer masking usethis?

Do you prefer masking usethis?

I would also prefer to update only Cargo.toml without wrapping the usethis function as you suggested.
