Feature Request: Integration with Git

[ligurio]

CASR already supports stacktraces produced by different programming languages.
I propose to integrate CASR with Git to easily figure out which git commit caused a given stacktrace.
Similar to git-stacktrace ¹, but it supports only three languages (Python, Java, JavaScript).

$ git stacktrace --since=1.day < trace
Traceback (most recent call last):
 File "webapp/framework/resource.py", line 72, in _call
   result = getattr(self, method_name)()
 File "webapp/resources/interests_resource.py", line 232, in get
   if self.options['from_navigate'] == "true":
KeyError

That's a great idea!

I suppose it could be even implemented in a more simple way. We can just call git blame (or even use some Rust-native git library) on crash line. And store the corresponding commit and author into Casr report.
