Socket reuse? #53
Description
I would like to know if it's possible to use the customer io client to send event/track requests using the same socket, either using HTTP/1.1 keep-alive or HTTP/2. A use case would be sending a specific email to all subscribers of an entity. The main API is causing a bit of overhead when you have to send more than one event/request.
Batch-sending could also fix it, but I assume that the server doesn't support it.
