filesystem.py: Introduce place-holder for BER-TLV files
I always assumed BER-TLV files are transparent EF with BER-TLV contents.
However, this is wrong. ETS TS 102 221 Section 8.2.2.4 specifies them.
TS 102 221 Section 11.3 describes the specific RETRIEVE DATA, SET DATA
commands, which are not yet implemented in pySim.
