LLD of type 'Script' times out on large payloads

Steps to reproduce:

1. Create an LLD rule of type 'Script', write some typescript that grabs a large json payload (>1000 objects).  See Zabbix-Meraki-Discovery as an example.
2. Discovery fails with a 'Timeout'

Result:
See screenshot.  It appears the timeout of 60 maximum seconds is not allowing the operation to complete.  It does work for smaller discoveries of less than 1000 objects.

Expected:
Expected would be a successful discovery of many objects.   Can the timeout be extended to 90 seconds or longer?
