Support chunked transfers in wget

[relic-se]

Chunked transfers are already supported within adafruit_requests but the content-length check within adafruit_portalbase.network.NetworkBase.wget (see below) prevents them from working because they leave that header omitted. (see https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/Transfer-Encoding#chunked for reference)

Adafruit_CircuitPython_PortalBase/adafruit_portalbase/network.py

Lines 336 to 339 in 25fc43d

	if "content-length" in headers:
	content_length = int(headers["content-length"])
	else:
	raise RuntimeError("Content-Length missing from headers")

This update extends wget to allow chunked transfers.

I've provided a simple demonstration using the Adafruit Fruit Jam to download the source files zipball from a GitHub repository which uses chunked transfer encoding.

I've provided more information in my investigation here: relic-se/Fruit_Jam_Library#12.

This update also includes compatibility fixes for adafruit_display_text version 3.4.0 related to outlined labels. (https://github.com/adafruit/Adafruit_CircuitPython_Display_Text/releases/tag/3.4.0)

I think we should wait a bit on changing this. Some of the device specific libraries that are use PortalBase are for devices with Display Text frozen in.

Unless users of those devices put the latest Display Text library in the root of CIRCUITPY, they won't have access to the newest version.

I think this should only change here after there is a new core release that includes the updated Display Text frozen in

[FoamyGuy]

It does unfortunately mean that when this library is in use on devices without frozen Display Text it will be printing that deprecation message.

Maybe we should disable the warning print for now and only turn it back on after that release is out so that updating is possible / easy for all devices.

I think I should be able to catch an ImportError so that it will work in both scenarios. Normally, I wouldn't want to touch this in the PR, but it was throwing an error in addition to the deprecation warning:

ImportError: cannot import name 'OutlinedLabel' from 'adafruit_display_text.outlined_label' (/opt/hostedtoolcache/Python/3.12.12/x64/lib/python3.12/site-packages/adafruit_display_text/outlined_label.py). Did you mean: 'outlined_label'?

Let me know if the most recent commit, cdbce86, works for you.

Portal_Base is also a frozen library. Maybe some code that checks if the Bitmap Label has outline_color or outline_size properties might work well enough.
