Also hand carried text to speech changes from Stable to master. Plus
unit tests for that.

If there are dropped packets during a burst download, the offsets and sizes
of the missing chunks are stored in a queue, and after the burst is
completed, they're requested individually.

This stores the last request and resends it after a timeout, with a max
of 6 retries.
It also checks for old incoming packets and drops them.

Some crazy shit in UAS.cc was using an array of 256 bytes to handle received messages and mapping them to components. Well, any message ID over 255 would cause a buffer overrun.
