[dimangopie]

1. Added a double slash '//' comment function.

2. Added a shebang '#!' line function.

3. Added a function that allows letters to replace symbols

   • default replacing mothed

   origin	optional
   '+'	'o' , 'O'
   '-'	'i' , 'I'
   '<'	'a' , 'A'
   '>'	'e' , 'E'
   '.'	'.' , '.'
   ','	',' , ','
   '['	'u' , 'U'
   ']'	'y' , 'Y'
   '#'	'?' , '!'

   • you can change them in src/brainfuck.c:other_char_table.\
   • I love these vowels, reading them is like listening to a baby trying to speak but only babbling.

4. Added two tools transLetter.py and transLetters.sh to help users automatically convert letters to others.

5. Add a tools folder to store transLetter.py and transLetters.sh.\
   You can compare the instruction parameters in transLetters.sh to customize the conversion file.

6. Removed the editline library dependency,
   because it was interfering with the NVIDIA 4060 GPU driver on my Ubuntu PC.
