ChunkedIO warnings

[Bradley Whited]

Excellent gem, thanks for making it.

If you run this code...

# test.rb
require 'down'

down = Down.open('https://github.com')
down.each_chunk() {|chunk| }
down.close()

...using ruby -w test.rb, you'll get a lot of warnings while downloading:

~/.gem/ruby/2.7.0/gems/down-5.1.1/lib/down/chunked_io.rb:304: warning: instance variable @next_chunk not initialized
~/.gem/ruby/2.7.0/gems/down-5.1.1/lib/down/chunked_io.rb:264: warning: instance variable @closed not initialized

This isn't a big deal, but fills up my log files if warnings are turned on.

Environment

• ruby 2.7.0p0 (2019-12-25 revision 647ee6f091) [x86_64-linux]
• down (5.1.1)

Thanks
