fix #18

Three functions GetFlag, SetFlag, ResetFlag are implemented to z80.GRP.
Those functions accepts a value of z80.Flag type.

Because z80.GPR is embedded to z80.CPU via z80.States, we can apply those functions on z80.CPU directly.
For example:

var cpu z80.CPU
carryFlag := cpu.GetFlag(z80.FlagC)

// this is equivalent to:
// cpu.States.GPR.GetFlag(z80.FlagC)
