Enhance timecrack.py: Encoding fix + Multiprocessing for faster cracking

[B4l3rI0n]

Fixes:

UnicodeDecodeError when using rockyou.txt or other non-UTF-8 encoded dictionaries by reading with latin-1 encoding.

Performance Enhancements:

• Rewrote the script using multiprocessing.Pool to support parallel cracking across all CPU cores.
• Cracking is now significantly faster with large dictionaries.
• Script stops checking once a password is found per hash (can be changed if needed).
• Added optional --workers flag to control number of CPU cores used.
