Custom avatar shape within ui5-li

Feature Request Description

Hi Team,
I am from successfactors, recently we are developing a page which renders a person list,
I am wondering if we can change the shape of avatar within <ui5-li>, I would like to set the shape to Circle, but by default it uses Square, and there's no way to change this property.

<ui5-li image={_getUserPhoto(person.userId)}>
      <ui5-title level="H5">{person.fullName}</ui5-title>
      <span>
          <ui5-label class={styles.email}>{person.email}</ui5-label>
          <ui5-label class={styles.title}>{person.title}</ui5-label>
      </span>
  </ui5-li>

Proposed Solution

It would be better if we can provide a property to custom avator shape.
