Update to use hypercore 11 in tests & as dev dep (#26)

* Update to use hypercore 11 in tests & as dep

* Properly teardown cores & monitors in tests

* Relax monitor test to check total bytes, not first update bytes

The bytes returned for the first `update` event were not always the max
buffer size (`65536`).
