Mask unions from commands

[Adrien5902]

The Problem

Mask unions are implemented in the code but can't be used via commands, only mask intersections using spaces can be used.

A Solution

some characters like pipes "|" could be used to separate them
but this would probably involve precedence parsing using parens or something

This is a known limitation of the current mask system, as it was mostly written with blocks in mind rather than generic masks. Intersections work fine with blocks themselves, just not any more complex masks.

The intention was to largely rewrite the way masks work in WorldEdit 8; there were some rough drafts done up for a plan a while ago (eg this), but it's one of those things where there's been a lot of other stuff with higher priority that's needed to be done first before we could really take a look at WE8. My hope is that once 7.4 is out, we can start properly looking at WE8 changes.

In general to do this properly, it'd likely need some form of grammar defined similar to what we do with the Expressions system
