Support for allowOtherValues attribute in Enum (Dictionary)

[ubermanl]

When testing against a given data dictionary, from a market, found that the allowOtherValues attribute is ignored, hence when a tag has an enumerated value, unknown to the dictionary, the library issues a Reject.
In particular this is happening since the market does not provide a full list of the reject reasons, and when a reject is received, a reject of the reject is emited.

<field number="103" name="OrdRejReason" type="INT" allowOtherValues="true">
      <value enum="0" description="BROKER_EXCHANGE_OPTION" />
      <value enum="1" description="UNKNOWN_SYMBOL" />
      <value enum="2" description="EXCHANGE_CLOSED" />
      <value enum="3" description="ORDER_EXCEEDS_LIMIT" />
    ... more values ....
</field>

For what i can tell, i guess is here where this validation should be "skipped" if such attribute is present in the dictionary tag for the message:

quickfixn/QuickFIXn/DataDictionary/DataDictionary.cs

Lines 352 to 370 in 4415618

	public void CheckValue(Fields.IField field)
	{
	if (FieldsByTag.TryGetValue(field.Tag, out var fld))
	{
	if (fld.HasEnums())
	{
	if (fld.IsMultipleValueFieldWithEnums)
	{
	string[] splitted = field.ToString().Split(' ');
	foreach (string value in splitted)
	if (!fld.EnumDict.ContainsKey(value))
	throw new IncorrectTagValue(field.Tag);
	}
	else if (!fld.EnumDict.ContainsKey(field.ToString()))
	throw new IncorrectTagValue(field.Tag);
	}
	}
	}

allowOtherValues is from Quickfix/j. Is there any plan to support it?

Thanks!.
