Auto detection of new line format in lexical analyzer

[amirbawab]

Option 1: Add the option to AUTO detect new line format in user input file: CR, LF, CRLF, instead of manually specifying it in the lexical JSON config.

{
    "newline": "AUTO",
    "..."
}

Enhancement:

• Add AUTO option in EasyCC-CPP/src/lexical/Lexical.cpp function Lexical::generateLexicalTokens()

Edit:

• Added Option 1

Option2: Allow user to execute an action function while traversing the state machine. An action function can increment the line number when a \n character is consumed.
