When using the msnodesqlv8 library, values passed into a BigInt column as strings are incorrectly cast using parseInt. This results in an incorrect value.

For example:

const value = "9223372036854775807";

console.log(value);
// 9223372036854775807

console.log(parseInt(value));
// 9223372036854776000

SQL Server can cast the string to a BIGINT implicitly, so I'm not really sure why a cast is required in the library at all. But no matter what the case, the current logic seems to result in bad data.
