Add option to disable automatic crash reporting

[jsahoo]

Description of the change

I use Rollbar for error logging but another tool for crash reporting. In older versions of the SDK, it was possible to initialize Rollbar without a crash collector. After updating, I found that there was no longer a way to do that. This PR adds a configuration flag that allows automatic crash reporting to be disabled by preventing RollbarCrashCollector from being initialized:

let config = RollbarMutableConfig()
config.isCrashReportingEnabled = false
Rollbar.initWithConfiguration(config)

Automatic crash reporting is enabled by default, so you only need to set this property when you explicitly want to disable crash reporting.

This is good, thank you for taking upon yourself to address this, @jsahoo!

Did you consider making this a flag on RollbarConfig instead of a parallel state+method overload?
