-Infinity values are not handled correctly in JSON

[rajsite]

A user found that when using UnflattenFromJSON for double arrays, if the JSON string encounters -Infinity then:

1. The node errors with code -375011
2. The node returns an array with partially parsed results

See forum: https://forums.ni.com/t5/G-Web-Development-Software/Bug-on-Unflatten-from-JSON/m-p/4361814#M702

Didn't thoroughly debug but scanning source the following line looks suspicious which seems to indicate that any negative value will not be treated like Infinity:

Agreed, it looks like that line will cause a -Inf to be treated as if it was an overflow a few lines below and return an error.

Created two AzDo bugs for the issue:

1. Lack of support for -Infinity
2. Returning partial / incorrect results on error (effectively user data corruption on error)
