GUANO specification not correctly implemented in ELEKON BatExplorer 2.1

[thorenson]

Due to a buggy timestamp creation, Elekon BatExplorer 2.1 (https://www.batlogger.com/en/downloads/batexplorer/software/be_2.1/) creates GUANO wavefiles with 7-digit milliseconds. strptime() in parse_timestamp() expects 6 digits for %f:
timestamp = datetime.strptime(s, '%Y-%m-%dT%H:%M:%S.%f') (line 126)
The function can't parse the timestamp and throws a ValueError. So the default guano-py cannot be used with Elekon wavefiles.

Apologies for the delayed reply; are you able to provide an original sample .WAV file from Elekon BatExplorer 2.1 (or similar)?

@thorenson Can you provide a sample .WAV file from the Elekon BatExplorer with this timestamp issue?
