Hint: the API in jv.h is for dealing with parsed JSON values, while the API in jq.h is for evaluating jq programs.

• Use jq_init() to allocate a jq_state * value,
• then use jq_compile_args() to compile a jq program,
• then use jq_start() to get ready to evaluate it on one input value,
• and then repeatedly call jq_next() to extract all the output values that the program produces.
• Termination is indicated by jq_next() outputting an invalid value (without a message),
• while errors are indicated by jq_next() outputting an invalid value with a message.
• When done, use jq_teardown() to release the jq_state * value.
