fix (infrared): send a longer low pulse at the end

HA is generating 0 length low pulses at the end of a frame.
But based on the captured data from remote sends, Tuya expects a longer pulse of 5-10 ms
Currently the remote is crashing after one successful command and cannot send again
for some time. But using the captured signals with the remote platform it is OK.

This has been the only difference I can find, so hopefully it can solve the problem.
