[query] please support a --basedir parameter to filter roots

[jessefarinacci]

I often want to run zoxide query --interactive in a large project and have the results all be at the project root where I'm invoking zoxide, not just the ones zoxide thinks are the most popular.

I propose a new --basedir [path] parameter to the query subcommand. If user passes --all we can error out or just preference one or the other. With --list and --interactive it will filter all results for having the same fully qualified path prefix specified by --basedir parameter, with the $CWD being the default value.

The query subcommand already supports an --exclusion mechanism for filtering. This new option to effectively invert that logic will also be valuable. Thanks!
