Request for feedback: debcraft update

Hi,

The command `debcraft update` can be run in a Debian packaging git
repository to automatically import a new upstream version along with
the usual steps before and after `gbp import-orig --uscan`.

If you are using Debcraft, I'd like to invite you to test the latest
version and give feedback on how well this works for you.

The `debcraft update` command automates these steps:

- ensure local git is up-to-date with remote git
- ensure remote git is up-to-date with what was last uploaded
- list all open MRs you might want to review before importing new versions
- fetch upstreamvcs and import with `gbp import-orig --uscan`,
potentially doing dual-import of upstream git tag if gbp.conf is
configured to do so
- rebase patches using `gbp pq`
- update changelog, commit and facilitate use of branch
`next/debian/latest` to easily file the new upstream import as a Merge
Request on Salsa for collaborators to review
- ..and more

When testing please use the latest Debcraft v0.9.2.
