Make error message appears only when error happen

[tame0001]

Currently, we are printing out status checking message every 10 seconds

rover-code/src/drive/drive/diff_drive.py

Line 61 in 587a146

self.dianostic = self.create_timer(10, self.dianostic)

rover-code/src/drive/drive/diff_drive.py

Lines 85 to 87 in 587a146

	def dianostic(self):
	for odrv in self.odrvs:
	odrv.check_errors()

This is not very helpful as it is hard to keep tracking critical messages. We should make this message shows up only when error happens.

I wrote this fucntion to check errors

rover-code/components/odrive/utils.py

Lines 38 to 44 in 587a146

	def get_errors(self) -> str:
	"""
	Return ODrive system errors
	"""
	# https://docs.odriverobotics.com/v/0.5.4/fibre_types/com_odriverobotics_ODrive.html#ODrive.Error
	errors = self.decode_errors(self.odrv.error)
	return " & ".join([ODriveError(error).name for error in errors])

We can work on top of this fucntion
