BigInt.parseInt ( string, radix )
The parseInt function produces a BigInt value dictated by
interpretation of the contents of the string argument according to
the specified radix.
The algorithm is the same as 18.2.5 but with the following edits:
* For all cases which result in returning NaN, throw a SyntaxError
exception.
* For all cases which result in returning -0, return 0n.
* Replace the second to last step, which casts mathInt to a Number,
with casting mathInt to a BigInt.
18.2.5 parseInt ( string, radix )
1. Let inputString be ? ToString(string).
2. Let S be a newly created substring of inputString consisting of
the first code unit that is not a StrWhiteSpaceChar and all code
units following that code unit. (In other words, remove leading
white space.) If inputString does not contain any such code unit,
let S be the empty string.
[...]
11. If S contains a code unit that is not a radix-R digit, let Z be
the substring of S consisting of all code units before the first
such code unit; otherwise, let Z be S.
12. If Z is empty, return NaN.
