JRuby Support

[aryeh-looker]

Curious if JRuby might be supported. Getting the following at the moment when attempting to install the gem by placing it in my Gemfile and running bundle install.

current directory: /Users/user/.rvm/gems/jruby-9.1.17.0@aryeh/gems/arg_scanner-0.3.0/ext/arg_scanner
/Users/user/.rvm/rubies/jruby-9.1.17.0/bin/jruby -r ./siteconf20190521-5756-1609kxo.rb extconf.rb

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

Provided configuration options:

extconf failed, exit code 1

To see why this extension failed to compile, please check the mkmf.log which can be found here:
