feat: a shorter alternative for "--stdin"

[balta2ar]

I really love the "--stdin" option -- my use case is searching for files globally using plocate and then piping them into eza:

plocate some pattern | eza -l --sort=size --stdin

I was wondering if it could be possible to add a shortcut for --stdin option. I'm thinking two options:

1. Determining whether stdin is there automatically, so that plocate something | eza would just automatically work.
2. Or/and -, e.g.: plocate something | eza -

Thank you!
