TP-Link T1500G-8T Vlans OID

There is no Vlan tab for this switch, because it's store its vlan list in different OID. Because of lack of vlan list, there is no fdb table with mac-address lists on ports.

[Here |https://static.tp-link.com/Supported%20Public%20MIBs%20for%20TP-Link%20Switches.pdf ] You can find all OIDs for this switch.

I've tried to manually add support for this by trying to change code of Observium but I'm to much of a noob to do so.
