Improve RPC to better match stock client

[SirenGlitch]

Is your feature request related to a problem? Please describe.
Can't use Open Party or Game Invites. No activity bar (I don't know what to call it) above user (shown below)

Describe the solution you'd like
Some form of adding the features mentioned. Not sure whether it's possible, might be something in OpenAsar's Discord Datamining that could work?

Describe alternatives you've considered
Have tried both the built-in Vesktop RPC and arRPC but the only difference I noticed was different game detection (Vesktop recognised MWIII as MWII, but arRPC got it right)

Additional context
No RPC buttons inside profile page either, just name and time played

https://github.com/discord/discord-rpc and https://discord.com/developers/docs/game-sdk/sdk-starter-guide may also have some helpful code

we rely on arrpc for RPC. See the arrpc issue for tracking this OpenAsar/arrpc#18

if arrpc implements it, vesktop will also get it. until then, i recommend you use stock discord instead of vesktop if you need these features
