Add Replugged support (and remove Powercord)

[Saltssaumure]

Powercord is kill, Replugged now uses asars for themes.

updater in manifest.json assumes that you'd want to have this published on the store (by submitting this and future updates in #theme-dev on the Replugged server) - if not, then it can be changed to update from GitHub instead:

"updater": {
	"type": "github",
	"id": "DiscordStyles/RadialStatus"
}

I think I might just add this to the bd-scss package behind a config setting.

What's the point of @parcel/config-default and @parcel/transformer-sass?
I don't see it referenced anywhere

[Saltssaumure]

They're plugins for parcel which is modular, both are required for building the asar from scss.

[Saltssaumure]

Turns out Replugged is switching from Parcel to esbuild in the next major update (replugged-org/replugged#541), will apply those changes here when the time comes.

Simple update if you're still interested in adding to the Replugged store.
