Module functions that take regex parameters fail

[Northern-Lights]

I have a rule that looks like this:

import "cuckoo"
rule domain {
  condition:
    cuckoo.network.dns_lookup(/example.com/)
}

yago fails with this error: {"lexical":"error","line":"4","msg":"Line 4: illegal regex modifier ())"}exit status 1

The method processCondition makes accommodations for module.variable, but it does not consider the following:

module.variable.<anything>
module.function(<anything

In this particular case, it believes that ) is being used as a modifier, when in fact it is used to end the function.

In the fix, functions with multiple parameters should be taken into consideration, e.g. if there is a , between parameters within the parentheses.

I'll review as soon as possible.
