Version 0.8.0

General changes

• display attribution in preview maps if present in tileset metadata.
• upgraded Docker containers to Go 1.17.
• upgraded Go version used for release to Go 1.17.
• switched to go:embed for embedding templates and static assets.
• dropped internal mbtiles package in favor of github.com/brendan-ward/mbtiles-go,
  which wraps the SQlite-specific go package crawshaw.io/sqlite for better
  performance.

Command-line interface

• added support for watching filesystem for changes to tilesets using
  --enable-fs-watch option.

Breaking changes

• now requires Go 1.16+.
• removes ArcGIS API layer info at the service root and layers endpoint (#116);
  this was not providing useful information for image tilesets.
• removed handlers.Assets; static assets are intended only for use in template
  or static file handlers.
• removed support for UTF Grids.

Bug Fixes

• fix handlers for ArcGIS API endpoints, resolving tile shift issue (#116).
• obviated incorrect include of node_modules in compiled asset file; executable
  is now smaller and faster to build.
