v0.10.0

Added

• Adds --playground-code-padding and --playground-code-line-padding for
  configuring code editor padding.

• Bare module specifiers are now transformed in dynamic import() statements.

Changed

• BREAKING The src/ directory is no longer published to NPM.

• BREAKING .js files are no longer compiled by TypeScript, so they cannot
  contain types, decorators, or other TypeScript-specific syntax.

• Previews will now begin loading immediately, instead of waiting for
  compilation to completely finish, and each .js file is served as it
  compiles.
