Subject: idevicecrashreport: Allow filtering crash reports by filename

Allows to filter crash reports by filename and copy only matching crash reports.

$ idevicecrashreport -u 00008020-001234 --filter MyApplication crash_reports
Move: /MyApplication-2019-07-29-164320.ips

This allows significantly improve speed of collecting only required crash reports.
