Add JQ_PATHS_ARGS to jq-paths

[Gerrit-K]

What?

This is a reopen from #24. It adds a new variable $JQ_PATHS_ARGS to the call in jq-paths to be in line with the usage in jq-repl and jq-complete.

Why?

This plugin can simultaneously support JSON and YAML with the help of gojq by simply setting:

export JQ_REPL_JQ=gojq
export JQ_REPL_ARGS=--yaml-input
export JQ_PATHS_ARGS=--yaml-input

However, actual yaml input will currently result in errors, which are likely caused by the jq-paths command not using the --yaml-input arg.
