MCOPY not supported

[SteMak]

The following contract crashes the tool with NotImplementedError in sfs_generator/ir_block.py at line 503

// SPDX-License-Identifier: MIT
pragma solidity 0.8.26;

contract MinimalSample {
    function enforceMCopy(uint256[] calldata input) external pure returns (bytes memory encoded) {
        bytes memory data = abi.encode(input);
        encoded = abi.encode(0x16, data, 0x17, data, 0x18);
    }
}

This happens due to the MCOPY opcode processing is not implemented

To resolve this, I suggest to implement the following change

    elif opcode == "EXTCODEHASH":
        _, updated_variables = get_consume_variable(index_variables)
        v1, updated_variables = get_new_variable(updated_variables)
        instr = v1+" = extcodehash("+v1+")"
         
     elif opcode == "MCOPY":
-        raise NotImplementedError
+        v0, updated_variables = get_consume_variable(index_variables)
+        v1, updated_variables = get_consume_variable(updated_variables)
+        v2, updated_variables = get_consume_variable(updated_variables)
+
+        instr = "mcopy("+v0+","+v1+","+v2+")"
+
     else:
         instr = "Error opcodes30: "+opcode
         updated_variables = index_variables
