Fix a panic in value export when an array has multiple types of arrays.
This takes into account the types of elements in sub arrays, slices, etc.
Fixes#279Fixes#377
Leverage github actions for tests and linting.
This includes fixing a bunch of issues highlighted by golangci
including:
* Dead code.
* Ineffectual assigns.
* Goto warnings.
* Nil return err.
* Reused literal strings.
* Test parameter order.
Also:
* Setup clog.
Previously, it was a publically accessible but invalid value (valueEmpty).
* Deprecate internal use of UndefinedValue(), NullValue(), FalseValue(), TrueValue()
* Guard against Empty, Result, Reference values from escaping the package
this allows you to export a javascript Value back
for use in go. the result structure should be the
same as if you serialized to JSON in javascript
and then Unmarshal'd those bytes in go
