While investigating this issue, the original RT22 was often experiencing read errors while cloning from the radio to CHIRP. It was eventually discovered that the radio was eventually missing an ACK at some point during the download which stopped the cloning process with an error.
This patch adds a small delay between the reading a block of data an the sending of the ACK back to the radio indicating that the block of data was received OK. The original RT22 radio now receives every ACK reliably.
