Remove support for legacy arguments (#9)

Closes #8

Remove deprecated `packageRoot` argument, nothing should be using this.

Change `sdkUri` to be statically a `Uri` for more type safety. We only
ever really need the String representation, but by enforcing the type we
keep usage more on the rails. The only usage in `package:test_core` is
passing a Uri, and other uses can easily wrap with `Uri.parse`.

Bump the minimum SDK to `2.4.0`. Not version of `package:test` will
support this package with a lower SDK bound, so it is not useful to
claim support for earlier SDKs that we can't test on.

source_map_stack_trace is a package for converting stack traces generated by dart2js-compiled JavaScript code into readable native Dart stack traces using source maps. For example:

import 'package:source_map_stack_trace/source_map_stack_trace.dart';

void main() {
  var jsTrace = // Get a StackTrace generated by dart2js.
  var mapping = // Get a source map mapping the JS to the Dart source.

  // Convert jsTrace to refer to the Dart source instead.
  var dartTrace = mapStackTrace(jsTrace, sourceMap);

This can convert the following JavaScript trace:
