Capture/report the Sdk Extension version

[yogurtearl]

Problem Statement

Right now the sdk captures the OS version, but not the Sdk extensions version.

Solution Brainstorm

call SdkExtensions.getExtensionVersion and add it to events and transactions. https://developer.android.com/guide/sdk-extensions#checks

Extensions would need to be a map. "R" -> 4 "S" -> 1 "T" -> 0

@yogurtearl thanks for the suggestion, the feature totally makes sense, we'll look into this soon-ish!

Could make sense to add it to our os context protocol defined here.
