pySim-trace: Add support for the TCA Loader log file format

The "TCA Loader" is a freeware utility program published by the Trusted Connectivity Alliance for testing SCP80, SCP81, SCP02 and SCP03 in UICCs. It can generate text log files of the APDUs it exchanges; let's add this file format to pySim-trace
