option to set radius group separator or get groups from each Class attribute without hardcoded Class format

Description of problem:

I use OpenLDAP as a source for Freeradius. For ocserv groups to work I need to send Class attribute in a hardcoded ocserv format "OU=group1;group1". The problem is that it is not possible to build Class in such format from LDAP groups. I can build using freeradius unlang Class in format "OU=group1,group2", where coma is used as a separator (hardcoded in freeradius unlang). The workaround is to use radiusClass LDAP attribute, but it complicates administration.

Version of ocserv used:

1.1.2

Distributor of ocserv

Debian 11

Expected results:

Configuration option to set group separator or set getting groups from separate Class attributes, eg: Class = group1 Class = group2
