unneeded trailing zero character on SNMP strings

[dima1308]

Please see attached screenshot
On each SNMP string on responce, there is an extra trailing zero character
Can you please check it?

This seems to be (from SNMPv2-MIB.yang):

     leaf sysDescr {
        type snmpv2-tc:DisplayString {
          length "0..255";
        }
       ...
        smiv2:oid "1.3.6.1.2.1.1.1";
      }

The type resolves to:

  typedef DisplayString {
    type string {
      length "0..255";
    }
    ...
     smiv2:display-hint "255a";

It seems that display-hint 255a is not handled correctly by Clixon (display-hint 255t is handled correctly).
A proposal is to treat 255a in the same way as 255t changing the string to an ASN.1 fixed string.
