[FEATURE] --json-schema should [be able to] take a file name

Problem Statement

The JSON data I'm using is 2k3, which is quite a large amount for the command line.

Proposed Solution

Now, granted, on MacOS, bash v3, this is 1MB. But it would be nice to have something like --json-schema file://my_large_schema.json, instead of --json-schema "$(cat my_large_schema.json)".
