Changes since 3.7.2

• In this major update we optimized a core part of the SSL handling. This results in large performance increases when downloading from news servers with SSL enabled. In addition, the general connection handling was improved, resulting in performance improvements for all news servers. Special thanks to: mnightingale, puzzledsab and animetosho!
• There are multiple settings that can tweak performance, see: #2474
• When adding a new news server, SSL is enabled by default.
• File assembly performance significantly improved by relying on the CRC32 instead of the MD5 to perform QuickCheck of files.
• Slowdown more gracefully when the cache fills up.
• Replaced separate Series/Movie/Date Sorting with general Sorter.
• HTTPS files are included in the Backup.
• Improved Watched Folder scanning and processing.
• Ignore resource fork files created by macOS.
• Deobfuscate final filenames is enabled for new installations.
• Dropped support for Python 3.7.
