Update module path, amqp091 dependency

[ghost]

This allows go get to pull version 2 of the module. Currently, attempting to upgrade to v2 of the module produces the following output:

go get github.com/cheshir/go-mq/v2
go: module github.com/cheshir/go-mq@upgrade found (v1.2.0), but does not contain package github.com/cheshir/go-mq/v2

Calling go get without /v2 installs v1.2.0.

On my fork (master branch) I created a tagged version v2.0.1 with the same changes (but updated module path), and was able to run go get -v github.com/calloway-jacob/go-mq/v2.

If this PR is accepted, I think it will also need a tag.
