Drag Plugin Gaps: check for CMD(meta) key to avoid page scrolling

[imabp]

Problem:

• Mac users natively uses Cmd + Scroll to zoom in and zoom out via Wheel Plugin
• But the following condition in the pixi-viewport Drag plugin implementation, restricts to zoom/in out using CMD + Scroll. Currently, pressing cmd+scroll have page scrolling effect instead of zooming.
• https://github.com/davidfig/pixi-viewport/blob/2e0ebcda0c6ee50c04e94bd86ff4a08a90f901a7/src/plugins/Drag.ts#L451

Proposal is to change the condition

FROM: (Current Implementation) if (!wheel || (!wheel.options.wheelZoom && !event.ctrlKey))

TO: (Proposed Condition) if (!wheel || (!wheel.options.wheelZoom && !(event.ctrlKey || event.metaKey)))

Thanks. A kind request to @davidfig , other respected contributors, maintainers to check the problem statement and their thoughts on it.
