Don't show objects that only in Stash

I'm torn about whether this and #1 should be the default behavior or whether they should be options. For example, --stash/--no-stash, --notes/--no-notes, and/or even more flexible options like --include=refs/pull/*/--exclude=refs/changes/*.

Meanwhile, as a workaround, git sizer --branches --tags --remotes might be close to what you want.

I think that git-sizer should warn about things like those that are uncommitted or things that are stashed. As @mhagger mentioned in #22, the goal of this project is to detect issues before they'd call for drastic action like a history rewrite.

This can now be accomplished using the new feature --exclude=refs/stash, introduced in #75. It could be made more convenient using helper options like --stash / --no-stash (see #77), but I'll nevertheless mark this wish done for now.
