rustic v0.10.0

[aawsome]

Hello rusticeans,

we are happy to release rustic 0.10.0. This release features various new functionalities including:

• Chunking can be customized using rustic init or rustic config. Moreover, fixed-size chunking has been added as option preventing potential chunking attacks and also improves backup performance for large files.
• rustic key commands have been added allowing management of repository keys/passwords
• Telemetry output has been added to the backup command supporting Prometheus and OpenTelemetry
• A diff view comparing snapshots/paths has been added to the interactive mode. This and the interactive ls mode also compute summaries for (sub)-dirs if requested.
• The new option delete-unchanged makes forget delete snapshots which identical to the previous one.

Note that some of the changes may slightly change existing behavior, those changes are marked as breaking below.
Notable is the removal of filter-fn. Please replace it with filter-jq.

Thanks a lot to everyone who contributed with code, issues or discussions!
