This contains some small tweaks to speed up the profiler. - changed from a namedtuple to a regular tuple as namedtuples were much slower but the tradeoff here is that it's more legible - moved away from `os.path.abspath` as it was doing some extra operations that were unnecessary for our use case

One benefit of this is that we're reusing the raw frame tuples across samples which helps with the overall memory usage as the number of duplicate frames across subsequent stacks can be a lot.

very cool to use the previous sample as a cache!
