Prepare for proj-sys v0.26.0 and proj v0.30.0 release (#230)

- [x] I agree to follow the project's [code of
conduct](https://github.com/georust/.github/blob/main/CODE_OF_CONDUCT.md).
- [x] I added an entry to the project's change log file if knowledge of
this change could be valuable to users.
  - Usually called `CHANGES.md` or `CHANGELOG.md`
  - Prefix changelog entries for breaking changes with "BREAKING: "

This updates libproj to v9.6.0, and bumps the `proj` MSRV to 1.82
(released 6 months ago)
I'd like to release these tomorrow (2025-04-18).
