Possible bug with `get_historical()`

[ReagentX]

User report: https://twitter.com/Frank_Hayes/status/1529034318785421312

I just started using it to look at data from se7488. The parent.get_historical() method with weeks =1 stops on May 10th.

[ReagentX]

Sample code:

from purpleair.sensor import Sensor
s1 = Sensor(7488, parse_location=True)
print(s1) 

# set the number of weeks of data to retrieve
weeks = 1

# Get the primary and secondary data for the first sensor location
df_s1_primary = Sensor(7488).parent.get_historical(weeks_to_get=weeks,thingspeak_field='primary')
df_s1_secondary = Sensor(7488).parent.get_historical(weeks_to_get=weeks,thingspeak_field='secondary')

df_s1_primary

Getting an error message now. Here is the traceback if it is any value.

This problem is related to the JSON API deprecation that happened a few days ago. See #69 for tracking that issue.
