making `Struct.omit` Dual
Could
Struct.omit (https://effect-ts.github.io/effect/effect/Struct.ts.html#omit) be made dual? Currently I either need to provide type parameters by hand, or do pipe(x, omit('key')) instead of omit(x, 'key'). I guess the problem is that it's variadic instead of taking a tuple of key names?
