How can I use a custom parcel plugin with Plasmo?

[steve-zhu-sh]

Some libraries might require build plugins like vanilla-extract: https://vanilla-extract.style/documentation/integrations/parcel/

Is there a way to use this library with Plasmo?

@steve-zhu-sh PR's welcome to just add it to the default config! - Otherwise we're not reading in extra config file atm <- PR is welcome to enable that as well (think it shouldn't be too hard)

Re: default config, push a PR to:
https://github.com/PlasmoHQ/plasmo/blob/main/core/parcel-config/index.json

Re: extra config file, the relevant code is:

plasmo/cli/plasmo/src/features/helpers/create-parcel-bundler.ts

Lines 66 to 74 in 0fcb84c

	const baseConfig = require.resolve("@plasmohq/parcel-config")
	const runConfig = join(dirname(baseConfig), "run.json")
	const configJson = await readJson(baseConfig)
	if (hasFlag("--bundle-buddy")) {
	configJson.reporters = ["...", "@parcel/reporter-bundle-buddy"]
	}

(The idea is that we would read-in an extra config.json from the user (prob use .parcelrc or the like), and replace/concat as necessary (the tricky bit is to ensure ppl not shooting themselves in the foot... but I think a naive implementation might work just fine)

Cool thanks for the suggestions! I'll see about putting up a PR when I find the time!
