Implemented torq simpleperf

Added functionality to validate simpleperf events, remove previous
files before beginning a new trace, pull trace files from the device,
and run simpleperf. Additionally, added device tests for new
functionality and a reference to simpleperf files that will be needed
for loading simpleperf in the web.
