Should the enclave be generic over URL?

[clangenb]

If I remember this correctly, we did this because we can't use Strings inside the runtime, but I am not sure if this is the right approach. Maybe we can just use PalletString as we use elsewhere:

pallets/primitives/common/src/lib.rs

Line 27 in be26e6b

pub type PalletString = Vec<u8>;

It shouldn't. I think we can define a safe bounded length for the url and use PalletString with BoundedVec

but I'd like the length of the bounded PalletString to be configurable by type argument.
This might make sense to solve together with #155 bounded types

Alright, makes sense to me.
