Two Net::ZMQ modules

[AlexDaniel]

There are currently two modules in the list:

• https://github.com/gabrielash/perl6-zmq “Net::ZMQ” but it actually provides “Net::ZMQ4”
• https://github.com/arnsholt/Net-ZMQ “Net::ZMQ” and it provides logically “Net::ZMQ”

For example, Cro::ZeroMQ depends on Net::ZMQ… although it's unclear which one. From what I understand, it is https://github.com/arnsholt/Net-ZMQ.

@GabrielaSH, @arnsholt can you please figure it out? Even if technically it might not be an issue, it confuses the hell out of me and I'm sure I'm not the only one.

Also, https://github.com/gabrielash/perl6-zmq doesn't compile:

Too late to switch language version. Must be used as the very first statement.
