✨ add rules for prototype members

[mysticatea]

Fixes #24.

Adding rules for prototype methods.

Those new rules are silent by default. Those will start to report disallowed prototype methods if you configured .eslintrc as using TypeScript or the aggressive mode.

---

Example 1, with TypeScript:

plugins:
- es
parser: "@typescript-eslint/parser"
parserOptions:
  project: tsconfig.json
rules:
  es/no-string-prototype-codepointat: error

Example 2, with Aggressive Mode:

plugins:
- es
rules:
  es/no-string-prototype-codepointat: error
settings:
  es:
    aggressive: true

Example 3, with TypeScript and Aggressive Mode:

(it reports prototype methods on any type)

plugins:
- es
parser: "@typescript-eslint/parser"
parserOptions:
  project: tsconfig.json
rules:
  es/no-string-prototype-codepointat: error
settings:
  es:
    aggressive: true
