There doesnt' seem to be `throwDecodeFile :: (HasCallStack, FromJSON a) => FilePath -> IO a`

though there are `throwDecode` and `decodeFile`

I think I didn't notice to add those, as I probably never used `decodeFile*` variants myself, but once they exist, it would make sense to have `throwDecodeFile` which would throw `AesonException`, won't it?

Locate the existing throwDecode and decodeFile definitions and read nearby tests or related decodeFile variants first. Add the missing throwDecodeFile API with the requested AesonException behavior, then run the relevant test suite and verify that the function is exposed consistently with the existing helpers.
