Subject: [PATCH] Remove the warnings cause by type declarations

Modify type declarations that raised deprecation warnings. These
were the warnings:

deps/hamcrest/include/hamcrest_internal.hrl:33: type set/0 is deprecated and will be removed in OTP 18.0; use use sets:set/0 or preferably sets:set/1
deps/hamcrest/include/hamcrest_internal.hrl:34: type gb_set/0 is deprecated and will be removed in OTP 18.0; use use gb_sets:set/0 or preferably gb_sets:set/1
