Update supported firmware to 1.0.6

- Bump firmware support to v1.0.6
- Add isAccessorySupportedWithAccessory: method
  that ignores non-whitespace and special characters
  since some older firmware has a comma in company
  name. This will also allow us to update the logic to use
  a whitelist of device SKUs etc in future.
  Not really sure if this method belongs in the GCSFirmwareUtils file. Thoughts?
