What's Changed

• Make copy of metric report when adding a report in the sdk by @gibbleyg in #64. This fixed an issue for heartbeat metrics and users of the sdk where metric report values were exponentially increasing. This bug did not affect users reporting metrics through the HTTP server, and only affects users of the sdk if they used the same struct for reporting a metric multiple times.
