example:
array with custom chips count:
```python

eeprom1 = EEPROM( i2c, addr=0x52, max_chips_count=2 )
```
1st array using address 0x50 and 0x51 and 2nd using array address 0x52 and 0x53.
individual chip usage:
```python
eeprom0 = EEPROM( i2c, addr=0x50, max_chips_count=1 )
eeprom1 = EEPROM( i2c, addr=0x51, max_chips_count=1 )
