Always 'write error' and 'No such device or address' messages on all my writing attempts

[developersu]

When I trying to write eeprom I see next error:

# cat dump1 | ./eeprog -f /dev/i2c-7 0x50 -w 0
eeprog 0.7.6, a 24Cxx EEPROM reader/writer

  Bus: /dev/i2c-7, Address: 0x50, Mode: 8bit
  Writing stdin starting at address 0x0
Error i2c_write_2b: No such device or address
Error at line 150: write error

I've fixed this by editing i2c_write_2b() from 24cXX.c file where I updated line 46 to usleep(10000); and this solved issue.

I can create a PR if you don't mind.

Thank you!
