Packs/Unpacks/Measures structs according to Python's struct format

npm install --save python-struct

const struct = require('python-struct');

struct.sizeOf('>iixxQ10sb') // --> 34

struct.pack('>iixxQ10sb', [1234, 5678, require('long').fromString('12345678901234567890'), 'abcdefg', true]); // --> <Buffer 00 00 04 d2 00 00 16 2e ab 54 a9 8c eb 1f 0a d2 61 62 63 64 65 66 67 00 00 00 00 00 00 00 00 00 18 80 01>

struct.unpack('>iixxQ10sb', Buffer.from('000004d20000162eab54a98ceb1f0ad2616263646566670000000000000000001880', 'hex')); // --> [ 1234, 5678, 12345678901234567890, 'abcdefg', true ]

When using "native" size & alignment, we do not really have a way to find the native size of alignment of types.
But it's almost always safe to assume that node.js is compiled for the standard architectures, so native behaves like standard.

If anyone stumbles accross a different case, I'll be happy to review it on that specific instance, and figure out what to do.

If you have anything to contribute, or functionality that you lack - you are more than welcome to participate in this! If anyone wishes to contribute unit tests - that also would be great :-)
