[Feature]: get required fields from request

[WatheqAlshowaiter]

Notes

Some people request to be able to get the required fields from request object.

It can be done using macros because Request class is macroable.

It may look like

$request->getRequiredFieldFor('TABLE_NAME_OR_MODEL') // name, email

if no table or name throw an exception.

Also, this may prefer the package to not in required dev
