Measured datasets errors

[praftery]

Several of the measured load profiles throw the following error when calculating emissions:

"cannot assemble the datetimes: day is out of range for month, at position 41. You might want to try: - passing format if your strings have a consistent format; - passing format='ISO8601' if your strings are all ISO8601 but not necessarily in exactly the same format; - passing format='mixed', and the format will be inferred for each element individually. You might want to use dayfirst alongside this."

e.g. Lab, 8909sqm, climate zone 3C

potentially a leap year issue?
