Mattias Wadman 518f6af4a8 gojq: Rebase fq fork
Upstream changes:
Many performance improvements
Error message improvments
Lots of refactoring

Most of the JQValue interface changes in gojq fork had to be reworked but
resultet in a much nicer and cleaner changeset.

fq changes:
Assignment to JQValue (like a decode value) now shallowly converts the value into
a jq value before assigning. Was a bit hacky as it was and this makes JQValue
behave more like real jq values. This also fixes some advanced indexing issues.

Actual custom path updates will be something for the future.
