Client can't handle chunked transfer encoding from api.thingspeak.com

This seems to be a revival of #56. api.thingspeak.com seems to be returning Transfer-Encoding: chunked starting some time around April 2020, as my sensors stopped being able to readRaw() with return code ERR_BAD_RESPONSE at that time. If I enable #define PRINT_HTTP, the client prints:

Got Status of 200
ERROR: Didn't find Content-Length header

Fetching from a computer via curl:

$ curl --http1.1 -H "Accept:" -H "User-Agent: tslib-arduino/1.5.0 (ESP8266)" -v "http://api.thingspeak.com/channels/9/feeds.json?results=0"

The two obvious fixes are either to fix the client to support chunked transfer encoding, or to turn off chunked transfer encoding on the server.
