Refactor Memory Reading

[MrTyton]

Most of the functions within the memory reading should be refactored to use this function

FFX_TAS_Python/memory/main.py

Lines 3344 to 3348 in 2cfcfc8

	def readVal(address, bytes=1):
	global baseValue
	key = baseValue + address
	retVal = process.readBytes(key, bytes)
	return retVal

makes the code a lot cleaner and easier to understand.
