rollbar vulnerable to prototype pollution

Description

Prototype pollution potential with the utility function rollbar/src/utility.set(). No impact when using the published public interface.

If application code directly imports set from rollbar/src/utility and then calls set with untrusted input in the second argument, it is vulnerable to prototype pollution.
