Description

Uses protobuf.js to decode the kndctr_ORG_ID_identity cookie and extract the ECID. Prototypes a getEcidFromCookie command.

Related Issue

Motivation and Context

We (recently) had a meeting with the Express team where they expressed their frustration that the getIdentity call to retrieve an ECID can take a while, and they use the ECID as an identity in a third-party analytics solution. We advised them to either extract the ECID from the AMCV cookie, or to use an FPID. But it is possible to extract the ECID from the cookie. The cookie is a url-safe, url-encoded, base64 encoded, byte representation of a protocol buffer

Unfortnuately, protobuf.js adds significant bloat to the library. The minified version gains a whopping 15 KB in minzipped size for a total of 55.120 KB. This is a significant increase in size for a library that is already quite large.
