si-tools: FM configuration improvements

Some changes to allow integration with the AGL radio binding and
improve FM configuration with some tweaks and additional configuration
options.

Changes include:
- Add command-line option for selecting FM band plan.  The default
  band plan is US / Canada.
- Add command-line options for setting FM scanning valid SNR and RSSI
  thresholds to allow tweaking sensitivity in poor radio environments.
- Increased seeking scan timeout to 3 seconds, which seems to improve
  behavior in poor radio environments where powerful stations may be
  far apart.
- Removed explicit setting of FM_SOFTMUTE_SNR_LIMITS, as it seemed
  like it might be resulting in odd muting behavior when scanning.
- Changed initial FM frequency if not specified to the minimum of the
  band plan.
