Simplify language

[flawrist]

Dear @dennis-tra, consider providing alternative for receive (or is it recieve, or recive?) command.
Simple get seems to work much better for those folks like me whose native language is not English,
or even omit this step (as croc does) with even simpler pcp <code>.

Hi @sergeevabc thanks for the suggestion, I was also considering doing it similarly to croc - I'll revisit that topic again. I was also considering fetch 🤔

Just for you to know, there is already the alias r for the receive subcommand. So pcp r would work exactly like pcp receive.
