Make better repr for PresetPosition

[ZLLentz]

Expected Behavior

It should be obvious what this object is and how to interact with it

Current Behavior

The repr is as follows:

pcdsdevices/pcdsdevices/interface.py

Lines 1382 to 1383 in b66e680

	def __repr__(self):
	return str(self.pos)

Which tricks us into thinking it's a float rather than an object.

Possible Solution

• Just remove the repr?
• Wrap with info PresetPosition(name='name', value=32434324)

Context

Made it difficult to find the deactivate method
