Suggestion: Add configuration init with data instead of url

[doozMen]

Hei I'm using, and loving, the formatting tool inside my code generator. I embed the config json file into the code as it is a cli tool that runs on linux. This means in my package manifest i use resources: [.embedInCode(swift_format.json)] which would not produce a url but data.

As the let config = try Configuration(contentsOf: url) only accepts an url would it be ok to make a PR and add an init that accepts data?

My current workaround is to create a temporary file but that seams like inefficient.

  let tempFile = try Folder.temporary
    .createFile(
      named: "swift_format.json",
      contents: Data(PackageResources.swift_format_json))

This could also serve as an enabler for the command-line tool for getting a future extension to pass the config as a string inline, like clang-format's --style="{key: value, ...}" 👍

Which version of the swift-format package are you using? This was added in #634, so it should be available in the 6.0 release.

The PR above also added this. We should probably update the README to reflect that, instead of just the argument help text.
