Feat: support `start` and `end` for positions

hi, I would like to display the popover beneath the element, right now the xPosition only support three options (‘before’, ‘center’, ‘after’) which doesn’t cover my use-case.

Ah ok that makes sense! I suppose it could be either,

xPosition: 'before' | 'start' | 'center' | 'end' | 'after';
yPosition: 'above'  | 'start' | 'center' | 'end' | 'below';

<sat-popover xPosition="start" yPosition="below"> ... </sat-popover>

or

overlapAnchorX: boolean;
overlapAnchorY: boolean;
overlapAnchor: boolean; // sets both X and Y to `true`

<sat-popover xPosition="before" yPosition="below" [overlapX]="true" [overlapY]="false"> ... </sat-popover>

Your suggestion is definitely less verbose, and I think easier to mentally picture. It would probably need to come with a breaking change to remove the overlapAnchor option.

Can you describe your use-case?

I would like to use it inside an input field, something like datepicker for material
