Every time pinpoint is called a new SourceMap.SourceMapConsumer object is created. Loading the source map into the consumer object is slow, so for multiple pinpoint calls the mapConsumer should be re-used.

Possible Solution

This change could be made without any changes to the API. However, caching the mapConsumer uses a lot of memory, so maybe this behavior should be opt-in only.

Maybe a cacheMapConsumers boolean could be passed into the StacktraceGPS constructor?

I can submit a PR if we can agree on an API.
