Doesn't immediately exit on dry run count

[hittjwX]

When running python3 sidecar.py --rss-feed https://www.spreaker.com/show/3257924/episodes/feed --directory /workspaces/obsidian/ --update --dry-run --limit 2 the script doesn't exit after two.

It seems to continue looking for markdown episode sidecars to process. Then, when it finds them, it keeps going. Expected behavior is to STOP after reporting two.

The collection of eligible files could stop once the limit is reached. This way, only the limit loops happen as inputs for the discovery code.

When using the --limit 2 on the update command line, it doesn't exit as it should.
