sle44xx: introduce decoder for Siemens memory cards

Introduce an initial implementation of the SLE44xx protocol decoder for
Siemens/Infineon SLE 4418/28/32/42 memory cards. ATR (Answer To Reset),
command and data bytes get displayed, and RESET/abort events are marked.
Extracted data bytes are made available as binary output.
