Feature request: JMESPath built-in functions

[dreamorosi]

Use case

As part of the JMESPath utility we need to implement the logic needed to support all the built-in functions (i.e. avg, max, min, ceil, etc.) defined in the JMESPath specification.

Solution/User Experience

Customers should be able to use these functions in their expressions like:

const payload = {
  grades: [1, 5, 2, 10],
};

const maxGrade = search('max(grades)', payload); // 10
const minGrade = search('min(grades)', payload); // 1
const avgGrade = search('avg(grades)', payload); // 4.5
const roundedUpAvgGrade = search('ceil(avg(grades))', payload); // 5
const roundedDownAvgGrade = search('floor(avg(grades))', payload); // 4
// ...

All the built-in functions defined in the spec should be supported.

All types, classes, and functions should be documented and exposed to customers via API docs.
