pw_transfer: Implement adaptive windowing in Python

This implements adaptive transfer windowing in the Python transfer
client. Window size is changed to be a multiple of the max chunk size,
and is increased in response to successful receipt of data and decreased
with packet loss. This follows an algorithm similar to TCP's
congestion control.

Pigweed

Pigweed is an open source collection of embedded-targeted libraries–or as we like to call them, modules. These modules are building blocks and infrastructure that enable faster and more reliable development on small-footprint MMU-less 32-bit microcontrollers like the STMicroelectronics STM32L452 or the Nordic nRF52832.

For more information please see our website: https://pigweed.dev/.
