Hero3+, error concatentating strings in overview

[jimdavcon]

Describe the bug Using examples with Hero3+, getting TypeErrors in call to overview method. Seems to complete the wifi connect and infoCamera and getStatus both complete successfully.

To Reproduce Using this code with miniconda:

`from goprocam import GoProCamera from goprocam import constants

print("get object...") gpCam = GoProCamera.GoPro(constants.auth)

print("get overview...") gpCam.overview()`

Screenshots Above python script produces the following output..

python go2.py get object... Connected to 10.5.5.9 get overview... camera overview current mode: Video current video resolution: 720p current photo resolution: 5mp m Traceback (most recent call last): File "go2.py", line 8, in gpCam.overview() File "C:\Users\Jim\miniconda3\lib\site-packages\goprocam\GoProCamera.py", line 1512, in overview print("current timelapse interval: " + self.parse_value(constants.Hero3Status.TimeLapseInterval, TypeError: can only concatenate str (not "NoneType") to str
