Added

• New Sender::fill function that fills a channel range with a value.
• Added NULL checking for the values pointer in Sender::set and Sender::set16Bit.

Changed

• No more volatile objects with weird copy constructors and assignment operators. Using atomic fences instead.
• Improved use of public, protected, private, and volatile.
• Sender::setPacketSize now disallows sizes of zero. The new allowed range is 1-513.
• Timeout detection in Flasher, USBProWidget, and the README now compare using strictly less than the timeout value so that the timeout value itself can be used to manually trigger a timeout, instead of having to use an arbitrary value greater than the timeout value.
• Changed uses of std::shared_ptr to regular pointers.

Fixed

• Ensure the packet size can't be changed in the middle of sending a packet.
• Improved lambda hygiene.
