Describe the bug

use alloy_primitives::{U256, U8};
use alloy_sol_types::SolValue;

fn main() {
    let data = U256::from(0);
    let encoded: Vec<u8> = data.abi_encode();

    let data2 = U8::from(0);
    let encoded: Vec<u8> = data2.abi_encode();
    // let encoded: Vec<u8> = alloy_primitives::Uint::<8, 1>::abi_encode(&data2);
}

It will give the error: no method named abi_encodefound for structalloy_primitives::Uint in the current scope for the U8 data.
The above U256 has no errors.

This is a known limitation: we specialize SolValue for Vec<u8> to encode like bytes, and for Vec<T> to encode like T[].
