bug: interval value parsing

[KirillKurdyukov]

linq2db/linq2db#4954 (comment):

As I mentioned now it could lose precision due to use of microseconds and double instead of ticks

ydb-dotnet-sdk/src/Ydb.Sdk/src/Value/YdbValueParser.cs

Lines 96 to 100 in 5ec38b4

	public TimeSpan GetInterval()
	{
	EnsurePrimitiveTypeId(Type.Types.PrimitiveTypeId.Interval);
	return TimeSpan.FromMilliseconds((double)_protoValue.Int64Value / 1000);
	}
