cannot use constants which depend on generic parameters in types

[nbgl]

This compiler warning pops up a bunch of times. It seems to only affect things that call Poseidon.

   = warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!

The Rust tracking issue is rust-lang/rust#76200.

These warnings are suppressed by #![allow(const_evaluatable_unchecked)] which has been included in #353. This hides the problem which is arguably not a good idea, but the issue should be addressed by #326 so I reckon hiding the warning is okay.
