Request: savefile-derive as a feature flag for savefile

[SandaruKasa]

Removes the need to keep two versions in a Cargo.toml in sync.

Thank you for getting in touch!

Is the idea that we introduce a feature flag that can be used to automatically pull in the correct version of savefile_derive, and then re-export the savefile_derive-macros from the savefile crate?

Sounds like a good idea. I'll take a look.

The feature flag has been added, and shipped in savefile 0.16.2.

Just reopen this or write a new bug if you have further suggestions!

Thank you a lot!
