Use Segment's Analytics-Csharp library to prevent deadlock #28
Description
PR #27 introduced a workaround to a deadlocking problem. In response to the bug report we submitted to SegmentIO, they have created a new Analytics-Csharp library that we can use. It's not entirely clear to me why this couldn't be fixed within the existing library. The new library is in beta and I suppose it might take a bit of experimentation to see if the interfaces/functionality are compatible with the way we were using Analytics.Net.
