Fixed esm compatibility issues

[MarkusDeutschmann]

• added exports for esm & cjs and also types for:

  bowser-jr          -> "."
  bowser-jr/browser  -> "./browser"
  bowser-jr/engine   -> "./engine"
  bowser-jr/os       -> "./os"
  bowser-jr/platform -> "./platform"
  bowser-jr/compat   -> "./compat"
  

• needed to switch the core module to 'type: "module"' to make ESM happy
• also updated some dependencies (just minor ones)
• fixed example how to import 'bowser-jr/compat'
• increased the package version to 1.0.5
