Max size validator with multiple option

[ruisilva450]

For context, right now if we put a limit of 5mb on the overall selection like this:

<ngx-mat-file-input multiple [formControl]="form"></ngx-mat-file-input>
------------------------
form = formBuilder.control(null, { validators: [ FileValidator.maxContentSize(5242880 /* 5 MB (=5 * 2 ** 20)*/) ] });

It would be nice if we had the option to say the max size for each file when we have the multiple option as true.
Maybe something like this?

form = formBuilder.control(null, { validators: [ FileValidator.maxContentSize(
    bytes: 5242880 /* 5 MB (=5 * 2 ** 20)*/, 
    separate: true
) ] });
