feat: added U8, U64 and U128 into U250

[aymericdelab]

very simple pr to add intoU250 implementation for u8, u64 and u128

[milancermak]

Can you please add u16 as well so we cover all the primitive types?

[tarrencev]

I think we can have a single generic impl like:

Suggested change

	impl U8IntoU250 of Into<u8, u250> {
	fn into(self: u8) -> u250 {
	u250 { inner: self.into() }
	}
	}
	impl TIntoU250<T, impl TInto: Into<T, felt252>> of Into<T, u250> {
	fn into(self: T) -> u250 {
	let inner = TInto::into(self) ;
	// TODO: Bounds checks
	u250 { inner }
	}
	}

ooooh that's very cool indeed, well done

im stuck on a this error:

error: Plugin diagnostic: Trait `core::traits::Into::<dojo_core::integer::u250, dojo_core::integer::u250>` has multiple implementations, in: "dojo_core::integer::TIntoU250", "core::traits::TIntoT"
   --> RouteAuth:38:180
                          IWorldDispatcher { contract_address: world_address }.set_entity(dojo_core::string::ShortStringTrait::new('AuthRole'), (route.target_id, route.resource_id).into(), 0_u8, array::ArrayTrait::span(@calldata));

issue is that there's already an implementation TIntoT in the corelib so both are applicable in the case of:

commands::set_entity(
      (route.target_id, route.resource_id).into(), (AuthRole { id: route.role_id })
        );

where route.target_id and route.resource_id are both u250 already

is there a way to specify which impl you want to use in this case ?
