/**
* Returns the OID corresponding to a name
*
* What's returned in the associative array returned by loadX509() (or load*()) is either a name or an OID if
* no OID to name mapping is available. The problem with this is that what may be an unmapped OID in one version
* of phpseclib may not be unmapped in the next version, so apps that are looking at this OID may not be able
* to work from version to version.
*
* This method will return the OID if a name is passed to it and if no mapping is avialable it'll assume that
* what's being passed to it already is an OID and return that instead. A few examples.
*
* getOID('2.16.840.1.101.3.4.2.1') == '2.16.840.1.101.3.4.2.1'
* getOID('id-sha256') == '2.16.840.1.101.3.4.2.1'
* getOID('zzz') == 'zzz'
*
* @access public
* @return String
