support redis 5.0 commands

[dselivanov]

• fix problems with json parsing for API generation
• regenerate API to support redis 5.0 (redis doc commit db399bb9f3871a749bc14cc9d60761a7bfd73cf8)
• add .o. .so to gitignore

It seems signatures of some functions were change, thats why tests fail. I will update tests.

Hi @dselivanov did you get this working? I installed your fork but I'm having some issues:

> r <- hiredis()
> r$XLEN("mystream")
Error in redis_command(ptr, cmd) : ERR unknown command 'XLEN'
> r$XADD("mystream", "*", "sensor-id", 1234)
Error in redis_command(ptr, cmd) : ERR unknown command 'XADD'

Can I help with anything?

@dseynaev as I remember it was working fine. Do you have redis 5 running? looks like you redis version is < 5.0

@dselivanov I was indeed blindly assuming that my local redis version was recent enough... upgrading fixed it, thanks.
