Version 2 moves a good chunk of ir tx details that are (probably) specific
to providing raw IR data from userspace via lirc into the ir-core lirc
bridge driver, instead of having them in the hardware-specific drivers
themselves. This greatly reduced the complexity of the mceusb driver's ir
tx function, and generalized the tx interface better for a non-lirc tx
