MAX_OPC_FILETIME limit changed in 1.0.2

[robgom]

Describe the bug
After upgrading asyncua to version 1.0.2, including commit 4e2389e824f951688ff2a0b29b7b994dc409c9b5, tests for OPC UA implementation regarding date time stopped working. The reason was that condition in win_epoch_to_datetime was changed to lower value (basically replacing leading 9s with 0s).

Version
Python-Version: 3.8, 3.9, ... opcua-asyncio Version (e.g. master branch, 0.9): 1.0.2

Sorry about very short problem description - I'll try to update that myself or ask coworkers to do that.
