.equals() does not correctly handle big unsigned integers

[ruimoe]

Big unsigned Longs are not correctly checked for equality with a string.

Steps to reproduce:

see this JSFiddle

Expected behaviour:

.equals() returns true for given arguments

Actual behaviour:

.equals() returns false

Yeah, indeed, it looks the equals, and comp functions are not finished for the case of comparing signed and unsigned value.

const value = '10234114402585926231'
let l1 = Long.fromValue(value, true);
let l2 = Long.fromValue(value, false);
console.log(l1.eq(l2));
console.log(l1.comp(l2));

Incorrectly show false, and -1.
