Mapping '-infinity' to DateTimeOffset fails when used with Npgsql

The following code

var result = connection.QuerySingleOrDefault<Dto>("SELECT '-infinity'::timestamptz AS Value");

public class Dto
{
    public DateTimeOffset Value { get; set; }
}

throws a DataException: Error parsing column 0 (value=1/1/0001 12:00:00 AM - DateTime) with the stack trace:

   at Dapper.SqlMapper.ThrowDataException(Exception ex, Int32 index, IDataReader reader, Object value) in /_/Dapper/SqlMapper.cs:line 3706

Expected result is no exception thrown, DateTimeOffset.MinValue returned in Dto.Value

I'm using Dapper v2.0.123 and Npgsql v6.0.5

This issue might be related to the discussion here #1716 and the fact that Npgsql returns -infinity as DateTime.MinValue, which throws when casted to DateTimeOffset if local timezone is UTC+N. Could it be somehow treated as a special case then?

Start with the conversion path in SqlMapper.cs around the reported line 3706 and reproduce the sample using Npgsql's timestamptz '-infinity' value. Trace the DateTime-to-DateTimeOffset handling and add a regression test if the project has coverage for this path; done means the query returns DateTimeOffset.MinValue without throwing.
