Feature: Macros for JSONata

[gesteban]

Hi team,

We are querying an API that returns data in JSON but does not allow to filter by date, so we are trying to filter data retrieved by date using available options in this plugin. As far as I know, there are two options: JSONPath and JSONata.

In JSONPath we cannot longer rely on filtering due to security reasons.

And in JSONata, which allows filtering, macros are not enabled on JSONata processing. So I cannot simply go and filter by dashboard date $.data[createdAt < $__isoFrom()].

Not the same, but it may be also related with this other discussion.

Thanks for your efforts maintaining this plugin, its really useful.
