When sending large packets, the device FIFO may not be emptied fast enough and data can end up getting lost. Patina can handle this to some degree, but if the data lost is the checksum bytes, the stub does not realize the packet was finished and will just wait indefinitely for more data. This change forces the data to be sent in smaller blocks with delays in between to allow the device to catch up. Ideally this is replaced by proper flow control in the future.
This commit implements the automatic reload functionality provided by the Patina core. This involves the following steps: 1. Load the new core, and compress it. 2. Request the core allocate memory for the compressed data. 3. Write the compressed data to the core's memory. 4. Request the core to load the compressed data. 5. Switch the register state to jump to the new core.
