V2.4

QGNSS V2.4 focuses on bug fixes and interface optimizations compared to QGNSS V2.3.

Bug Fixes:
① Fixed the crash issue occurring during stress testing with large data volumes.
② Fixed the abnormal coordinate axis data display in GNSSLog when the module had no data output.
③ Fixed the stress testing anomaly regarding Time To First Fix (TTFF) for Online AGNSS.
④ Fixed the crash caused by closing and reopening the AGNSS window during TTFF stress testing.
⑤ Fixed anomalies occurring during the configuration of commands for certain modules.
⑥ Fixed the issue where baud rate switching was ineffective during the firmware upgrade process for certain modules.
⑦ Fixed the issue where Google Earth failed to launch when automatically opening the generated file in the NMEA-to-KML conversion function.

New Features:
① Added DOP chart display to GNSSLog.
② Added support for plotting full-band distribution curves by satellite in GNSSLog.

Optimizations:
① Optimized the signal level graph display to resolve incomplete rendering issues.
② Optimized the Firmware Update interface.
③ Optimized the format conversion method for map correction within the coordinate conversion function.
④ Improved the anti-crash mechanism for TTFF testing.
