BigInt `0n` Throws Error

[WilsontheWolf]

The BigInt 0n throws an error when serializing, unlike every other BigInt.

I found this is because 0n evaluates true in this if clause and the original value (as a bigint) is returned directly.

serialize-javascript/index.js

Lines 86 to 88 in 343abd9

	if (!value && value !== undefined) {
	return value;
	}

I'm not really sure what is the intention of this check.
