Title: Altered library to match structure of Adafruit_MCP23017

Altered library to match structure of Adafruit_MCP23017 library but used
MCP23008 info from MCP23008 datasheet.

Could never get original MCP23008 library to work but had no issues with MCP23017. Noticed how different they were, so I rewrote the MCP23008 library to match form and function of your MCP23017 library but used MCP23008 datasheet properties. After rewrite, the MCP23008 library and examples worked perfectly. Thought this would help out other customers who might be struggling like I was.
