[winswitch] [ANNOUNCE] Xpra 6.2.2

[Antoine Martin]

Hi,

This minor update to the v6.2.x branch contains some security fixes, 
please update.

The first security issue affects how authentication options are parsed.
Sockets defined using the newer `--bind-XXXX=host:port,auth=module` 
syntax would not apply the authentication module to connections upgraded 
to use SSL.
A possible workaround is to add `--ssl-auth=module`, or use `--bind-wss` 
/ `--bind-ssl=..` only.

The second issue is an overflow of the picture buffers when handling 
YUV-to-RGB format conversions for non-OpenGL windows.
A hostile server could potentially write user-controlled data beyond the 
end of the malloced buffer.

The self-contained SBOM script was also added to this branch, so all the 
MS Windows builds now include a complete SBOM file.
