[nostory] make `boost list-channel` output grepable
Context
- as a maintainer, i often want to grep the output of
boost list-channels
to see if a particular channel i just created is being used - due to how we were passing the output through
jq
, that was not working. now it does. (h/t: https://devops.stackexchange.com/questions/2928/how-can-i-pipe-jq-output/2931) - bonus: throw an error if
jq
is not installed when a maintainer invokes any command that needs it
