Macro for Environment parser

Usage

let variable: u8 = config!("U8_VAR");
let variable_with_default: i32 = config!("NOT_DEFINED_I32_VAR", 0);
// Automatically inferred that `variable_with_default_and_type_inferred` is u8 due to the default value
let variable_with_default_and_inferred_type = config!("VAR", 0u8);
