Upon a closer read of FROST paper, it seems like FROST is not geared at specifically improving factuality, and as such does not require a direct comparison against.
[x] Mention FROST & clearly argue how it's different from our approach

Addressed FROST a bit. It's short, but I think it's clear how it's faithfuless-oriented due to the fact that it extracts entities from the source (and is fundamentally intrinsic)
