The standard Python 'fix' for 'send()' returning prematurely is to use the 'sendall()' method instead. However, this method was not available. adafruit_httpserver will probably need to code a version of it for older versions or for Airlift, but when it's available this code works (Tested on picow sending 8192 bytes) and may be more efficient. (implementing 'sendall' in python should take care to slice a memoryview rather than the original buffer)
