astro 1.6.4

#5290 b2b291d29 Thanks @matthewp! - Handle base configuration in adapters

This allows adapters to correctly handle base configuration. Internally Astro now matches routes when the URL includes the base.

Adapters now also have access to the removeBase method which will remove the base from a pathname. This is useful to look up files for static assets.
