v1.8.0

This release contains a number of new capture features. It also removes support for Python 3.8.

• The new --disable-video-capture commandline flag allows excluding video captures in the brozzler-new-site commandline tool. (#379)
• When video capture has been disabled, brozzler will no longer browse YouTube UMP packets. (#378)
• Audio content types are now also skipped when video capture is disabled. (#380)
• It's now possible to control whether Chrome is launched in headless mode using the --no-headless commandline flag and the headless keyword parameter in the Chrome.start method. The default hasn't changed. (#373)
• Improved performance when visiting page anchors. (#394)
• Improved compatibility when fetching robots.txt and page headers by enabling legacy renegotiation and disabling errors from unexpected SSL EOFs. (#411)
• Fixed a bug which could break captures under certain specific circumstances when a page interstitial is encountered. (#375)
• The header request timeout has been increased from 30 to 60 seconds. (#367)
• Updated the versions of several dependencies.

Thanks to @TheTechRobo for the features in pull requests #373 and #394!
