added gitignore, encoder command functionality and enhanced error handling

[hastgt]

• Implemented encoder (knob) command functionality, as outlined in original comments:
  • Switched to encoder bank (IEN) before sending command, and back to key bank (ISW) after
  • Added prompt for user input with validation for difference values (range -32 to 31), converting input to two's complement byte
  • Constructed byte array in the required format <0x44, 'encoder id', 'ticks'> and added delay for reliable command processing.
  • Enhanced error handling for input errors and exceptions

- NOTE: Implementation is untested on actual BKM-10r hardware

Additional Improvements:

• Consistent Indentation: Adjusted indentation style to 4 spaces across the main script
• Exception Handling in connect Method: Added specific handling with Exception as e to provide detailed error messages on connection failure
• Channel Name Update: Validated channel number input in updateChannelName, ensuring values are between 0-9 to improve error handling
• Error Handling for Unsupported Characters in writeText: Added try-except to catch unsupported characters in writeText, notifying the user accordingly
• Enhanced User Prompts in sendCommand: Included range validation and detailed error messages for encoder inputs in sendCommand
• Command Output Logging: Logs the current command list for debugging purposes in sendCommand
• Command Listing in Main Loop: Main loop now includes a help command listing all available commands, a feature missing in EmuBKM-10r.py
• Default COM Port Handling in Main: Improved default COM port handling with bkm = EmuBKM10r('COM9'), whereas EmuBKM-10r.py lacked explicit handling

I'm not sure when I'll be able to test the knobs, but it would be extremely helpful if you could check whether they're working correctly and merge it into the main branch

I can definitely check functionality to ensure it works as intended! Thanks again for taking a look at this and improving it! Ill update here with the results before I merge this.
