Rename muon binary from muon package

[Andrea Pappacoda]

Hi Pino, I'm sending this email to you directly as I saw that you've 
been maintaining the muon package since 2017 (even if the last upload 
has been in 2019).

Could you please help me with a conflict regarding the /usr/bin/muon 
binary? You can find the full context in my previous email, here:

Bye :)
