Description:
    This script generates SHA-256 hashes for various escape sequences in Python and saves them to a file.

Escape Sequences:
    \': Single quote
    \": Double quote
    \\: Backslash
    \n: Newline
    \r: Carriage Return
    \t: Horizontal Tab
    \b: Backspace
    \f: Formfeed
    \v: Vertical Tab
    \0: Null Character
    \\N{Name}: Unicode character Database named lookup
    \\xhh: Character with hex value hh

Requirements:
    - Python 3.x

Usage:
    To use this script, simply run it in a Python environment.
    Ensure Python 3.x is installed on your system.

Additional Notes:
    - The script calculates SHA-256 hashes for each escape sequence listed in the ESCAPE_SEQUENCES dictionary.
    - The resulting SHA-256 hashes, along with their meanings, are saved to a file named 'sum_escape_sha256.txt'.
    - The output file is formatted in JSON for easy readability and parsing.
