Failure library is being deprecated

[proycon]

I happened to come across the news that the failure crate is being deprecated, and was aware this library is used by rust-bert: see rust-lang-deprecated/failure#347

This probably isn't a priority, but something you might want to be aware of at least.

Hello,

I agree and have seen the news too. For now rust-bert relies on tch-rs which still uses Failure. I am keeping the dependency for a similar "feel" between the two libraries. I would recommend raising it to the tch-rs author. If required the Failure crate is only lightly used and replacing the Faillible<()> by Result<T, Err> should not require too much effort.

Thank you for raising this
