Subject: [PATCH 02/36] feat(ipv6): add the ability to enforce IPv6 usage

Add `pubnub_set_ipv4_connectivity` and `pubnub_set_ipv6_connectivity` functions to make it possible
to enforce specific protocol usage.

test(message-type): add subscription test for custom message type

Modify subscription integration with additional information about custom message type to check
parsing.

Subject: [PATCH 28/36] feat(ipv6): add connectivity setter

Add `pubnub_set_ipv4_connectivity` and `pubnub_set_ipv6_connectivity` to `pubnub_coreapi` to switch
preferred connectivity protocol.

fix(proxy): add proxy context reset on connection close

Make sure that in case of connection close (including because of error) proxy context object will
be reset.
