Browser tests fail

[colinsullivan]

Heyo,

Buffer class is used in test.js which is not available in Browsers:

Uncaught TypeError: Buffer.alloc is not a function
    at getBuffer (test-bundle.js:11774)
    at module.exports (test-bundle.js:11774)
    at Test.<anonymous> (test-bundle.js:11788)
    at Test.bound [as _cb] (test-bundle.js:8090)
    at Test.run (test-bundle.js:8103)
    at Test.bound [as run] (test-bundle.js:8090)
    at next (test-bundle.js:7900)
    at test-bundle.js:5322
    at Array.forEach (<anonymous>)
    at MutationObserver.<anonymous> (test-bundle.js:5321)

Related, Buffer.alloc isn't in iojs, so those tests are failing on travis:

https://travis-ci.org/colinsullivan/js-opc/jobs/375627474

/home/travis/build/colinsullivan/js-opc/strand.js:21
    return Buffer.alloc(input * 3);
                  ^
