Additional options for OBJECT functions

Additional options have been added to OBJECT_PATHS, OBJECT_PAIRS_NESTED and OBJECT_FILTER:

exact [boolean](default: false)

Indicates the pattern used should be an exact match for the field or path (according to the "patternspace" argument).  It is a short-cut for the regular expression start (^) and end ($) anchors but can be used when "regex" is false too.

ignorecase [boolean](default:false)

Causes the pattern to be matched ignoring case.

A further option has been added to OBJECT_PAIRS_NESTED:

report [string: "field" or "path"](default: path)

Controls the content of the resulting "name" field selecting between either the full path or just the final field name.
