Improve logging reliability and fix export consistency issues

[mitsuki31]

Overview

This pull request addresses several issues related to logging reliability and export inconsistencies. The changes focus on ensuring that errors are logged appropriately and that the exported members are correctly named for consistent usage.

Key Changes

Fixes

• 925ceec - Ensure that logging is done before exit:
  • Updated the writeErrorLog function to include a promise chain that ensures logging completes before the function exits. This prevents any race conditions and ensures that error logs are reliably recorded before the error is handled.
• b0f04e8 - Replace the logging method:
  • Replaced the direct use of process.std*.write with the utils.logger methods in the validateYTURL function. This change improves logging control and makes the logging process more reliable and consistent with the rest of the codebase.
• 443f627 - Fix mismatch in exported members' names:
  • Corrected the naming of exported members in the index module to ensure they match the intended export names. This resolves an issue that has persisted since change Add VERSION_INFO constant for more structured version information #33, and we apologize for any inconvenience this may have caused.

Summary

These fixes are essential for maintaining the stability and reliability of the ytmp3 module, particularly in error handling and logging processes.
