3.19.0-beta.3

• Adds a desiredAccuracy param to Radar.trackVerified() and Radar.getVerifiedLocationToken(). Use MEDIUM (default) for medium accuracy (generally prefers wi-fi) and lowest latency, or HIGH for highest accuracy (generally prefers GPS) and slightly higher latency.
• Adds Radar.clearVerifiedLocationToken() to clear the last location token (e.g., on logout).
• When calling Radar.startTrackingVerified(), if the last location token is valid, avoids fetching a fresh location token immediately and simply schedules the next location check.
