a new turbo system support: Low Silesia Turbo 2000 (lowsil2000). This is almost identical with cs2000, the only difference is the length of piloting signal
a fix to --endtime option, end time is now determined more precisely
a change to output files naming scheme was made in the routine which avoids overwriting existing files (filename_1.log, filename_2.log ... instead of new_filename.log, new_new_filename.log ...)
ToDo list
support for more turbo formats (appropriate tape dumps and Atari utilities needed)
automatic recognition of tape format (standard/turbo/type of turbo) in audio files (probably beyond my skills)
