bump dep, reworked yandex cookie, enabled GA real-time tracking

Fixes #25 & #19's comments regarding real time tracking. Tested & works on live GA deployment.
I couldn't figure out how. I tried constructing the cookie w/ tough-cookie's [`.fromJSON`](https://github.com/goinstant/tough-cookie#fromjsonstring) but test fails with `TypeError: Cannot call method 'trim' of null`. Request doesn't integrate all of tough-cookie's APIs. The docs are somewhat confusing. But this works right?
