Bump addressable to 2-4 min

[mindbat]

Should fix #42

Bumps the addressable dependency to >= 2.4. This should make us compatible with logstash (and logstash plugins) for 7.x and up.

Passes tests locally (after some fudging with the documentation of methods and constants, which is beyond the scope of this patch):
