Reading trace file allFiredEvents fails silently on large files.

[rudolfix]

readFileSync will fail on files larger than ~260MB as described here.
nodejs/node#9489
This will make solidity to fail with cryptic message when calling toString on the readFileSync results.
We encountered this problem due to (relatively) large number of tests we run on our code base.

Solution: use stream to read line by line as in this commit Neufund@9a041d7
If maintainers are interested I can provide PR.

Whoa! That's a lot of events! Thanks for reporting.

Yes we'll happily take as a PR! Thank you @rudolfix.

@rudolfix Absolutely no pressure here but is your preference to open a PR or is it more convenient for you if we just steal this? With attribution of course.

If PR that's great, and take as long as you like :)

Do you have gitter channel? All tests are passing except app test which throws on timeout

1) app "before all" hook:
     Error: Timeout of 60000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves.

I run it with npm run test. I'd like all tests passing before I push PR

@rudolfix I DM'd you there.
