Before this patch:
$ ./pySim-shell.py -p 0
Card reader initialization failed with an exception of type:
<class 'pySim.exceptions.ReaderError'>
after:
$ ./pySim-shell.py -p 0
Card reader initialization failed with exception:
No reader found for number 0

We had a mixture of tab and 4space based indenting, which is a bad
idea. 4space is the standard in python, so convert all our code to
that. The result unfortuantely still shoed even more inconsistencies,
so I've decided to run autopep8 on the entire code base.

Make sure that a reader is disconnected before connecting it. This will
efectively prevent resource leakage in the lower PCSC layers when the
reader is connected multiple times during bulk provisioning

* add type annotations in-line with PEP484
* convert existing documentation to follow the
"Google Python Style Guide" format understood by
the sphinx.ext.napoleon' extension
* add much more documentation all over the code base

Unfortunately, Debian ships old Python (3.5 vs 3.8) and old pyscard
(1.9.4 vs 1.9.9). Calling PCSCCardConnection.disconnect() from a
destructor causes warnings about ignored exceptions:
AttributeError: 'NoneType' object has no attribute 'disconnect'
AttributeError: 'NoneType' object has no attribute 'setChanged'
AttributeError: 'NoneType' object has no attribute 'SCardDisconnect'
TypeError: 'NoneType' object is not callable
All these exceptions happen in pyscard's own destructors.

From pyscard user's guide [1]:
== Selecting the card communication protocol ==
By defaults, the connect() method of the CardConnection object
will try to connect using either the T=0 or T=1 protocol.
To force a connection protocol, you can pass the required
protocol to the connect() method.
This means that a PC/SC ifd handler may automatically choose T=1
as the highest protocol if the card indicates both in its ATR [2].
Since pySim only supports T=0, let's select it explicitly.
