Getting error for calling save() method

[vzaletny]

Hi.

Caling method save() for a changed object get an error:
File "/opt/python3.6/site-packages/pynetbox/core/response.py", line 358, in save
diff = self._diff()
File "/opt/python3.6/site-packages/pynetbox/core/response.py", line 333, in _diff
{fmt_dict(k, v) for k, v in self.serialize().items()}
File "/opt/python3.6/site-packages/pynetbox/core/response.py", line 333, in
{fmt_dict(k, v) for k, v in self.serialize().items()}
File "/opt/python3.6/site-packages/pynetbox/core/response.py", line 329, in fmt_dict
return k, "".join(v)
TypeError: sequence item 0: expected str instance, int found

In file pynetbox/core/response.py
Line: 329
return k, "".join(v)
should change to
return k, "".join(map(str, v))
