@example
```ts
    const obj1 = { name: 'jiojio', addressInfo: 'zoo', list: [{ appInfo: { level: 10 } }] }

    const result = keyname_to_snakecase(obj1)

    assert

        .equal<typeof result>()

    assert.equal(result, { name: 'jiojio', address_info: 'zoo', list: [{ app_info: { level: 10 } }] })
```
@example
```ts
    const obj2 = { MATE_INFO: 'uus' }
    const result2 = keyname_to_snakecase(obj2)
    assert.equal(result2, { mate_info: 'uus' })
