extend is also a reserved word

[recursethis]

I ran into a deserialization issue with a proto that had a field name called "extend"
It may be best to skip calling send() for any of ruby's reserved words and not just "class"?

logstash-codec-protobuf/lib/logstash/codecs/protobuf.rb

Line 303 in 65454f6

value = input.send(key)

the field name caused a deserialization error with the following stack trace

org.jruby.exceptions.ArgumentError: (ArgumentError) wrong number of arguments (given 0, expected 1)

"method" is also a reserved keyword; the plugin tries to run any field with that name during parsing.
That's quite a bummer, because Elastic's own recommended schema, ECS, has one such field - http.request.method

I managed to trigger this- seem like "test" is also a reserved word.
