Add delays in reset during firmware upload.
Change goto back to function call to jump to 0x0000. Both probably work
but any other address and goto seems to fail.
Attempt to get example working for ATTiny4313. OK when first programmed.
Corrected some old settings in the defines header.
goto statement used wrong address. Go back to the function call.
Still has a problem with reliability.
Doesn't jump to bootloader when asked.
