add addtional service to ProvideServicesAdvertisement

[easyg_trycode.txt](https://github.com/adafruit/Adafruit_CircuitPython_BLE/files/15119831/easyg_trycode.txt)
when running the code i get error
Traceback (most recent call last):
File "", line 21, in
File "adafruit_ble/advertising/standard.py", line 197, in __init__

AttributeError: 'list' object has no attribute 'uuid'

what is the meaning of advertisement = ProvideServicesAdvertisement() does it advertise all services ?

import time
from ble_packet_buffer_service import PacketBufferService
from ble_json_service import SensorService
from adafruit_ble import BLERadio
from adafruit_ble.advertising.standard import ProvideServicesAdvertisement
from adafruit_ble_adafruit.temperature_service import TemperatureService
from adafruit_ble_adafruit.humidity_service import HumidityService
from adafruit_ble.services.standard import BatteryService

ble = BLERadio()
ble.name= "ZP"
pbs = PacketBufferService()
service = SensorService()
advertisement = ProvideServicesAdvertisement()

temp_svc = TemperatureService()
temp_svc.measurement_period = 1000
temp_last_update = 0

humidity_svc = HumidityService()
humidity_svc.measurement_period = 100
humidity_last_update = 0

battery_svc = BatteryService()

addtional question does PacketBufferService could interfere SensorService ?

Start with adafruit_ble/advertising/standard.py, especially ProvideServicesAdvertisement and extend, then reproduce the traceback using the attached easyg_trycode.txt example. Determine the intended handling of the supplied services and document or test the expected behavior, including whether PacketBufferService and SensorService can coexist.
