Custom language support

[arnav56745]

Hi, its me again. ** 3 Issues in one repo! ** Anyway, I want custom language support for editor Like

class MyLexer:
      keywords = ["echo", "rmdir", "if"]
e = Editor(root, lexer=MyLexer)
e.pack()

@arnav56745 sorry for the delay (uni)

since cupcake uses pygments this will be easy to setup! https://pygments.org/docs/lexerdevelopment/#regexlexer https://pygments.org/docs/lexerdevelopment/#using-a-lexer

[tomlin7]
