• Remove unused dependencies.
• Update unassertify to 2.x.
• Use @browserify/envify. It's the same as @goto-bus-stop/envify, just renamed.
• Use @browserify/uglifyify, with support for more modern ES features.

• breaking Update terser. Tinyify now requires Node.js 6.
• Use patched envify from npm as @goto-bus-stop/envify.

• Use a patched version of envify with support for newer syntax features.

• Update common-shakeify to 0.6.0, this should have no observable effects.

• Update common-shakeify to 0.5.2+, which fixes a syntax error issue, and which can remove exported functions that are only used inside other unused exported functions.

Remove direct dependency on uglify-es, use terser 3.7.6+.

Revert to using uglify-es pending release of terser/terser@9255757

• Update uglifyify to v5.
  This aligns the uglifyify --debug flag handling with tinyify's. Chances of anything being broken before this patch are very small though.

• Add bundle-collapser when --no-flat is passed, to still save some bytes even if browser-pack-flat is not used.
• Automatically disable bundle-collapser and browser-pack-flat when the --full-paths option is passed to Browserify

add API to easily apply tinyify to other browserify pipelines, like generated by factor-bundle or split-require.
