tenderly_setCode lets you deploy arbitrary bytecode to an arbitrary address. This is useful for testing purposes, for instrumenting contracts that take part in the test.
When deploying modified bytecode, the verification information will no longer match and it will not be possible to access traces and debugger for target addresses.
