rec2rec - AttributeError: 'Namespace' object has no attribute 'mib_source'

[Dale Schultz]

Running the command to convert snmpwalk to snmprec, I encounter this error.
I installed master from this repo 2 weeks ago. Using Python 3.6.8 on CentOS Linux release 7.7.1908 (Core)

[user@server data]$ snmpsim-manage-records --input-file=modem.snmpwalk --source-record-type=snmpwalk
Traceback (most recent call last):

Its a typo and there are some more similar naming errors I fixed in #142

Could you please suggest how you resolved the "AttributeError: 'Namespace' object has no attribute 'xxx'" issue?

There is a similar issue #147, want to see if I could fix it by follow your way.

Thanks,
