Update macro.py

[bDgcgsX4bnc3Duprdb2S]

Add macro support for args and kwargs
Eg: """set ip {{ ip | IP | macro("myfunc", "arg1", "arg2", key="value") }}"""

TODO: Fix macro doc saying macros are based on exec (they are NOT) and describe new args and kwargs behavior

Hello, thank you for PR, could you advise what is the usecase for that?

[bDgcgsX4bnc3Duprdb2S]

Imagine trying to build a date from a string with a specific format:

• template="""set date {{ date | re(...)| macro("datetime.strptime", "%d/%m/%y %H:%M:%S.%f") }}"""
• data="""set date 31/01/22 23:59:59.999999"""

BTW and FYI, this fix unfortunately won't work with group macros because they are implemented differently.
