DateTime64 values less than 1970-01-01 cannot be read

[MaceWindu]

From error it looks like values read as UInt64 instead of Int64

System.OverflowException
  Message=The value 0xFFCD8C88F2850000 is greater than the maximal value of the type "System.DateTime". It is only possible to read this value as "System.UInt64".
  StackTrace:

   at Octonica.ClickHouseClient.ClickHouseDataReader.GetFieldValue[T](Int32 ordinal)

I have the same problem. I think this project isn't maintained anymore. I'll try to fix that in my fork.

Edit:
I submitted a pull request for this issue. If you still can use it and can't wait for the pull request to be merged, you can use my fork: https://github.com/MrDoe/ClickHouseClient

I changed ranges of supported values to [1900-01-01 00:00:00, 2299-12-31 23:59:59.99999999] for DateTime64 and to [1900-01-01, 2299-12-31] for Date32. Also, the client doesn't return default(DateTime) for 1970-01-01 anymore.

The bug was fixed in the version 3.1.2.
