It's a common pattern to use Box<dyn std::error::Error> to represent any type of error. However, if you try to convert a frost_core::Error<C> into it, the compiler requires adding a 'static bound to the function (e.g. <C: Ciphersuite + 'static>. The reason is explained here.

We can simply add the 'static bound to Ciphersuite ourselves, which would then not require doing it in every function that uses that pattern. (This came up while converting the demo code to use generics).

This is a breaking change (and a simple one) so I think we can add it to the 2.0.0 release.
