powerAssertContext reducer function to parse assertion expression at runtime.

Use this function when transpiler side does not add ast, tokens and visitorKeys at compile time.

var appendAst = require('power-assert-context-reducer-ast');

var appendedContext = appendAst(powerAssertContext);

Given powerAssertContext object, having structure below but does not have ast, tokens and visitorKeys, append them to output context.

input:

        content: 'assert(foo === bar)',
        filepath: 'test/some_test.js',
        line: 1
    },
    args: [
        {
            value: false,
            events: [
                {
                    value: "FOO",
                    espath: "arguments/0/left"
