Merge pull request #46 from wrtlprnft/fix_set_address 
Fix enumeration failure after loading the riscv-usb-cdcacm.

Foboot v1.9+ now requires the USB device set the address, otherwise it will not respond.  This patch adds a proper response to the `SET_ADDRESS` host request and fixes compatibility with Foboot v1.9+.
