[XS] Change in pysim[master]: filesystem: add command to delete all contents from a BER-TLV EF

laforge has submitted this change. ( https://gerrit.osmocom.org/c/pysim/+/37917?usp=email ) Change subject: filesystem: add command to delete all contents from a BER-TLV EF ...................................................................... filesystem: add command to delete all contents from a BER-TLV EF When working with BER-TLF files, we can only delete one tag at a time. There is no way to delete all tags at once. This may make working with BER-TLV files difficult, in particular when scripting is used and the script needs to start with an empty file. Also export has problems, since it does not reset the file before setting the new values there may be unexpected results in case there still tags in the file that are not set during import. To fill the gap, let's add a commandd that deletes all tags in a BER-TLV EF at once.
