Add InputFormat and InputCulture attributes to have more fine grained control of Reading

[Tamayi]

I am receiving some CSV files where I receive dates in the format yyyyMMddHHmmss and sometimes, yyyyMMdd. I would like to be able to desrialise these into proper DateTime objects.

06|T|1|NHRPL|57999|Minor Theatre|M|12000|T|20080414105034|20080414125034||AC||0|1|0|0|0|0|P||

The .NET framework allows parsing these values as:

string value = "20080414105034";
DateTime.Parse(value); 'FAILURE
DateTime.ParseExact(value, "yyyyMMddHHmmss", CultureInfo.InvariantCulture); 'SUCCESS

If we could optionally pass in those through settings, then it would really help to deal with these non-standard formats. Sometimes, the data does not follow standard formats for the FileCultureName property. This would then allow this sort of configuration:

[CsvColumn(FieldIndex = 9, InputFormat="yyyyMMddHHmmss", InputCulture="", OutputFormat="yyyyMMddHHmmss")]
public DateTime TransactionDate { get; set; }
