Bug#937480: pymia: Python2 removal in sid/bullseye

[Gert Wollny]

Hi Sandro, 

NMU is fine with me, as nearly all the packages in debian-med the
package is lowNMU, so no delay is necessary. 

Maybe next time consider to send the diff as merge request on salsa, it
makes it easier to apply ;) 

Best, 
Gert
