Takes a [folded stack samples file](https://github.com/brendangregg/FlameGraph#2-fold-stacks) and a regex pattern to to filter for specific stack frames and folds them again. This is useful when you want to profile a program that runs on multiple processes and want to aggregate stack frames regardless on which process they ran on.
import re
from collections import namedtuple
import click
OCCURENCES_PATTERN = re.compile(r"\d+$")
FoldedStack = namedtuple("FolderStack", ("stack", "occurences"))
