pw_transfer: Support protocol v2 in Python client

This updates the Python transfer client to work with either the legacy
or version 2 transfer protocols.

To support this, a wrapper class around the generated protobuf Chunk
class is implemented, supporting serializing and deserialzing specific
sets of fields based on the protocol version in use and type of chunk.

To set the protocol version, a default can be provided when constructing
a transfer manager. Alternatively, version can be set on a per-transfer
basis when starting a new transfer. As with the C++ client, the default
version remains LEGACY until all transfer implementations are ready to
switch over.

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/.
