Add in ability to search for objectSID by specifying the binary data

[gwillcox-r7]

Right now its possible to do queries like this to retrieve an object by SID in other clients such as Apache OpenDirectory:

(objectSid=\01\05\00\00\00\00\00\05\15\00\00\00\6b\91\19\c4\89\0a\a3\69\bb\50\52\c2\07\02\00\00)

However it doesn't seem possible to do this within Net::LDAP and in fact if one tries to do this no results are returned. Is there any way to do this properly within Net::LDAP as this seems to be an open issue with the project from what I've gathered from previous questions related to this topic in the issue tracker.
