Fix some issues in test_10_82_3

[garethsb]

I hope this fixes a few issues:

• The ptpPattern previously allowed lowercase hex digits, but the ABNF in RFC 7273 uses RFC 5234 HEXDIG, which only accepts uppercase.
• The ptpPattern previously accepted the pre-RFC 7273 errata form for ptp-domain-name. (The resolution deletes the domain-name= prefix, similarly to the ptp-domain-nmbr case, which is already correct in this test.)
• However, the ptp-domain-name form is in any case only used for IEEE 1588-2002 (v1), not 2008 (v2), so isn't necessary for ST 2110-10.
• After the earlier update to the test to match the RFC 7273 traceable ABNF, the message about supported PTP versions needed updating.
• In order to capture other unexpected extra trailing characters, I've added a $ to the end of the regex, which means the check for !ptpMatch[4] && ptpDetails.endsWith(':') is no longer required since that case will be caught by the earlier one (!ptpPattern.test(ptpDetails.slice(14)))
• I don't believe the domainNmbr error could have fired before, since ptpMatch[4] includes the colon, so +ptpMatch[4] would always have been zero. I've changed this to ptpMatch[5].
