Get a Typescript typed environment variable value from `process.env` (NodeJS) with type casting for booleans, strings and numbers
View env.ts
* Return an environment variable typed value from `process.env`.
* It also supports a default value in case of `undefined`.
* The function will follow these steps to take a typed value:
* 1. First it will try to get the env value from `process.env`.
* 2. Then if `undefined` then it try with the default environment variable value if defined.
* 3. Otherwise if the default value is `undefined` then it will return the Javascript default values:
* - Boolean: `false`
* - String: `""`
