v1.6.3

Changed:

• The macOS app bundle now uses Python 3.10 instead of 3.9. This comes with some performance improvements.

Fixed:

• Work around transitory server-side errors when refreshing access tokens by retrying the refresh up to five times.
• Fixed a segfault on startup for a small number of macOS users.
• Fixed an issue where files which contain decomposed unicode characters could be deleted after renaming them locally on some versions of macOS.
• Fixes an issue where the maestral gui command would fail for macOS app bundles.
