[ Feature ] Manual override for memory offsets in league-observer-tool

[figyl]

Almost every time a patch comes out Game memory offsets change, therefore Fairsight is down. (For example, we have a broadcast day today and 13.6 just dropped, we can't use fairsight.)

It would be great to have a manual override option for the memory offsets in league observer tool, so that the offsets can be updated on demand without having to wait for the official update.
