BigInt.toInt could be zero-cost

Small thing, if wanting to some compile-time overhead. It also is a good deal faster for me at runtime

https://github.com/rescript-association/rescript-core/blob/main/src/Core__BigInt.res#L16

@scope("BigInt")
external toInt: (@as(32) _, bigint) => int = "asIntN"

Sure would be nice if we could bind a rescript external function to a js expression for the **:

external exp: (t, t) => t = %rawExpression("%{1} ** %{2}")

My mistake, this doesn't actually convert to Number unfortunately.
