Checks up to 10 UK EORI numbers (GB or XI followed by 12 or 15 digits) with HMRC

Checks up to 10 UK EORI numbers (GB or XI followed by 12 or 15 digits) with HMRC's public check: valid or not, with the processing date. HMRC does not publish the trader's name in this check, so it is null. An HMRC outage is a 503, not charged, never 'invalid'. EU EORI numbers are refused with a 400 in this version.
