Request: Add filesize to library view

[guy-holland]

Thanks for this skin which is basically perfect. The only thing I miss from other skins is the ability to see the size of a video file in GB when browsing the library. Average bitrate would be cool too but filesize would be fine and I know that's already possible as it's in other skins like the default skin.

For me it's useful for seeing at a glance for seeing whether something is a low quality encode or a remux etc. Sometimes I'm only in the mood for watching something uncompressed that's gonna look really good on my TV.

If it displayed alongside the resolution, aspect ratio, audio channels etc. that would be the perfect place for it.

Didn't want to create a similar issue, so will add this here.
Can you please also add file sizes to the list views (esp. in Files mode) like in estuary.
Thank you!
