Hi,

I'm a big fan of the plugin and have been using it for years. Thank you for all your hard work!

As you probably know, using Composer in a WordPress plugin or theme can conflict with other plugins when they've also using Composer.

I've run into an issue where sometimes the version of wp-background-processing I'm using is different to the one another plugins pulls in, causing a problem where my code is using the version pulled in by the other plugin, not the version I've pulled in.

Are you open to adding namespace to the classes in this package? I'm more than happy to attempt a PR for this myself.

If so it'll mean I, and others, can use tools such as Imposter to prefix the class namespaces which will prevent this issue.
