run_speakeasy parameter parsing

[mwilliams31]

The run_speakeasy.py argument --params doesn't work as intended for an example like --params -log -path <file_path> because argparse treats -log as -l og. A possible solution is to treat the --params argument as a string and perform additional parsing, which could also account for items like <file_path> that may have additional spacing considerations. The updated --params argument would look something like --params="-log -path '<file_path>'".
