Suggestion: replace go-libsecret

Hello-

I have forked `github.com/gsterjov/go-libsecret` as `r00t2.io/gosecret` (GitHub mirror as `github.com/johnnybubonic/gosecret`) and rewritten it (I maintain two branches; `v0` for backwards-compat and `v1` and onwards for a much-improved API). Among such improvements are:

* [Full documentation](https://pkg.go.dev/r00t2.io/gosecret@v1.0.1)
* Drop-in compatibility with go-libsecret (see docs) in the `v0` branch
* Gofmt'd code
* MUCH easier to use functionality
* And *full* functionality, matching SecretService spec
* With extensibility supported, as the Dbus connections/objects for each struct are now exported.
* And much more.

Please feel free to let me know if it serves your purposes better.

If you do use it, I recommend exporting the underlying structs so that a keyring may be typeswitched into the original and the methods for those structs able to be used by users of this library. 👍
