Changes

pySim.esim.saip: Implement optimized file content encoding

Make sure we make use of the fill pattern when encoding file contents:
Only encode the differences to the fill pattern of the file, in order
to reduce the profile download size.

pySim.esim.saip: Don't try to generate file contents for MF/DF/ADF

only EFs have data content

pySimLogger: user __name__ of the module when creating a new logger

At the moment we use random identifiers as names when we create a
new logger for pySimLogger. Let's switch to consistently use the
module name here. For the top level modules let's use the program
name so that it will show up in the log instead of __init__.

transport/init: use PySimLogger to print messages

The module still uses print to output information. Let's replace
those print calls with the more modern PySimLogger method calls.

tests/pySim-smpp2sim_test: add integration test

At the moment pySim.ota codebase is not covered by any of the
integration tests (we have only normal unittests so far). To
increase the test coverage, let's add an integration test that
sends exchanges an RFM OTA-SMS with a real-world card.

However, there is no tool avaliable that can be used as an SMPP
client for pySim-smpp2sim yet. Let's use smpp_ota_apdu2.py on
laforge/ota to develop a tool that we can use to exchange SMS-TPDUs
that contain remote APDU scripts (RFM/RAM).

Finally let's use the tool we have created as a basis to create
an integration test that exchanges an SMS-TPDU with the RFM
application of a sysmoISIM-SJA5 card. The testcase shall pass
when we get the expected response from the card.
