avrpgm: add EEPROM support also, verify all 3 first bytes of SPI commands. I'm not sure why I wasn't doing that, probably because I was getting a lot of AVR err and thought that only 2 bytes of the cmd were echoed. But now, with a reliable SPI setup, verifying 3 bytes seems to work. 2020-10-06 10:32:42 +11:00			`: aspe@ ( addr -- byte, read from EEPROM )`
