Invalid TypedData encoding with specific int/uint sizes (e.g. int24) #25932
Description
System information
Geth version: 1.10.25
OS & Version: Ubuntu 20.04.5 LTS
Description
Typed Data providing int/uint types that differ from the primitive golang types are not supported while being valid Solidity types.
According to EIP-712 atomic types of type int/uint can be a size ranging between 8 - 256 bits
Expected behaviour
Should be able to successfully encode typed data with valid int/uint types between 8 - 256.
Actual behaviour
Encoding fails due to unknown primitive type.
Steps to reproduce the behaviour
package main
import (
"github.com/ethereum/go-ethereum/common/math"
"github.com/ethersphere/bee/pkg/crypto/eip712"

typedData := eip712.TypedData{
