0.15.2

Fixes:

• Native/Windows: Resolve correct symbol names for crashes in multi-module apps (#1811)
• Crashpad: Resolve correct symbol names for crashes in multi-module apps (#1813, crashpad#156)

Features:

• Added an in-process app-hang detection. When enabled via sentry_options_set_enable_app_hang_tracking, a background thread monitors the application and captures an app-hang event if no heartbeat is received within app_hang_timeout (default 5000 ms). Call sentry_app_hang_heartbeat() regularly from the thread you want monitored. (#1806)
