Error Writing file with file size >2GB

Normal case var value = 2147450880:

$ node
Welcome to Node.js v20.17.0.
Type ".help" for more information.
> var value = 2147450880
undefined
> var hi = (value / 0x100000000) | 0;
undefined
> var lo = (value & 0xffffffff) | 0;
undefined
> hi
0
> lo
2147450880

lo is still positive

Error case var value2 = 2147659776:

> var value2 = 2147659776
undefined
> var hi2 = (value2 / 0x100000000) | 0;
undefined
> var lo2 = (value2 & 0xffffffff) | 0;
undefined
> hi2
0
> lo2
-2147307520

lo2 becomes -2147307520 indicate an overflow

This fix use js native buffer.writeBigUInt64BE and buffer.readBigUInt64BE to write js Number into a 64 bit buffer
