Add --card-format command line switch to override card validation

[uhppoted]

Ref. https://github.com/uhppoted/uhppote-core/issues/15

The UHPPOTE controllers seemingly support Wiegand-34 (and possibly other) card formats making the Wiegand-26 validation introduced in v0.8.5 problematic for some systems. However, the validation is useful in avoiding incorrect card numbers due to finger trouble and it would be better to keep it in place.

Proposal is to add a --card-format <format> command line switch to the put-card and put-acl commands override the default validation. The format would take the following initial values:

• wiegand-26
• wiegand-34
• any (no validation)

[uhppoted]

• [x] Rework put-card to accept card formats parameter
• [x] Add Wiegand-34 validation to uhppote-core put-card
• [x] Add any validation to uhppote-core put-card
• [x] Update uhppoted-lib to include card.format in uhppoted.conf
• [x] Add (optional) --card-format command line parameter to put-card
• [x] Add (optional) --card-format command line parameter to put-acl
• [x] CHANGELOG
• [x] README

Seems Wiegand-34 is a "user defined" standard:

Implementation complete - pending release.
