Option to send raw values

[CravateRouge]

Option to send already encoded values calling MSLDAPClient.modify. Disabled by default to not disturb tools already using this function.
I also added LDAP_WELL_KNOWN_ATTRS in the available lookup tables to increase encoding possibilities

[skelsec]

is this one still needed?
What do you think of a solution that instead of introducing a new input variable we could allow the users to send a custom object like LDAPCustomValue that has an encode method which the user can implement the encoding logic in?

That's a very good idea, it's even more flexible
