Document how to use bootloader

[xobs]

While the protocol is well-documented, there is no documentation on how to use it.

In the programmer directory it says to run tinyprog -l, however it doesn't say how to use tinyprog.

There is a setup.py, however it doesn't work:

❯ python .\setup.py
Traceback (most recent call last):
File ".\setup.py", line 4, in <module>
    from setuptools import setup, find_packages
ModuleNotFoundError: No module named 'setuptools'

There is a directory called tinyprog, and surprisingly Python seems to recognize this, however it doesn't work either:

❯ python tinyprog
Traceback (most recent call last):
File "D:\obj\Windows-Release\37amd64_Release\msi_python\zip_amd64\runpy.py", line 193, in _run_module_as_main
  File "D:\obj\Windows-Release\37amd64_Release\msi_python\zip_amd64\runpy.py", line 85, in _run_code
  File "tinyprog\__main__.py", line 10, in <module>
    from six.moves.urllib.request import urlopen
ModuleNotFoundError: No module named 'six'

It's telling you you don't have setuptools installed. setuptools is required to run setup.py for many, if not the majority, of setup.py scripts out there.

This is all completely standard fare for installing Python packages, it shouldn't be particularly surprising or hard to figure out.
