[fix] Use dynamic require for bufferUtil and utfValidate

[Mike-Dax]

Closes #1756

Upon attempting to require the utf-8-validate and bufferutil modules, Yarn PnP will detect the usage of a module that's not installed and error.

This replaces the requires with a dynamic require call that doesn't get caught by Yarn PnP (or other bundlers for that matter).

Thanks for the PR but I'm not a fan of this. Both bufferutil and utf-8-validate are marked as optional peer dependencies

ws/package.json

Lines 37 to 43 in 78e1c01

	"peerDependenciesMeta": {
	"bufferutil": {
	"optional": true
	},
	"utf-8-validate": {
	"optional": true
	}

so this issue should be solved by yarn or other bundlers, not here.
