Changelog

Support for safely serialising objects to json, guided by the schema, with new function json_serialise
New object json_schema for construction of reusable validation and serialisation functions

Always uses ES5 version of Ajv, which allows use in both current and “legacy” V8 (#51)

Upgrade to ajv version 8.5.0
Add arg strict to json_validate and json_validator to allow evaluating schema in strict mode for ajv only. This is off (FALSE) by default to use permissive behaviour detailed in JSON schema

Schemas can use references to other files with JSON pointers i.e. schemas can reference parts of other files e.g. definitions.json#/definitions/hello
JSON can be validated against a subschema (#18, #19, @AliciaSchep)
Validation with error = TRUE now returns TRUE (not NULL) on success
Schemas can span multiple files, being included via "$ref": "filename.json" - supported with the ajv engine only (#20, #21, @r-ash).
Validation can be performed against a fraction of the input data (#25)

Add support for JSON schema draft 06 and 07 using the ajv node library. This must be used by passing the engine argument to json_validate and json_validator at present (#2, #11, #15, #16, #17, @karawoo & @ijlyttle)
