upsert function and accompanying tests

[eakray]

Implemented function for polymorphic updating or inserting in one operation

Polymorphic over arrays, objects, and Maps.

Issues:

• not sure if the style is sufficiently functional
• not sure if the type signature is correct
• not quite sure what kind of error handling should be supported
• not sure how to fill out the @SInCE and @see fields of the jsdoc comment

Please let me know if I can make any improvements to the PR. Thanks.

Sorry, I mistakenly thought I might not get a response as the original issue is a bit old. Please disregard the closing.
