`globalThis` undefined

[Dave]

in deck.gl 6407 deck.gl replaced global with globalThis.

Rstudio doesn't appear to like this and can't find globalThis.

I don't know if this is correct, but this solution at the top of mapdeck.js seems to solve it. But I have no idea of the downstream consequences

if( typeof globalThis === 'undefined') {
	var globalThis = window;
}
