onionshare: Request for backport

[Aidan Gauland <aidalgol@fastmail.net>]

Dear onionshare maintainers,

I am writing to request a backport of the bullseye release of onionshare
to buster.  I have had a very low success rate in transferring files
with the buster version, and have had no issues with the bullseye
version (built from the bullseye source package on my buster system). 
(I should note that I have only used the commandline interface, so I do
not know whether there would be any issues with running the GUI from the
bullseye version on a buster system.)

Kind regards,
Aidan Gauland
