--config doesn't handle anything with commas

[walkerburgin]

I'm attempting to configure swc to use a custom plugin via the command line as part of a larger build process. Essentially I'm trying to replicate this .swcrc:

{
    "jsc": {
        "experimental": {
            "plugins": [
                ["./my_plugin.wasm", {}]
            ]
        }
    }
}

Calling swc --out-dir=dist --config=jsc.experimental.plugins=[[\"my_plugin.wasm\", {}]] src/ fails with an error like this:

invalid type: string "[[\"my_plugin.wasm\"", expected a sequence at line 1 column 187
Failed to compile 1 file with swc.
Error: Failed to compile:

I poked around a little bit, and here's what swcOptions ends up set to:

{
  jsc: {
    parser: undefined,
    transform: {},
    experimental: { plugins: '[["my_plugin.wasm"' }
  },
  sourceFileName: undefined,
  sourceRoot: undefined,
  configFile: undefined,
  swcrc: true,
  '': true
}

I think the collect() function (here) splitting the input on commas is causing the truncation.
