uhd.js

WebAssembly and WebUSB build of UHD 4.0, with a multithreading-friendly shim of the libusb async C-API in Javascript, in order to compile UHD and Boost to WebAssembly mostly unmodified.

The demo initializes an Ettus USRP B200/205/210 and streams IQ data to a waterfall plot, all within a Chrome browser-tab.
