[FR] Make height set automatically to get a square card

Consider the code:

type: custom:map-card
entities:
  - entity: zone.home
card_size: 8.65

A value for card_size was defined to make the card looking square - like a stock map card:

On that picture:

ha-map card with a default card_size;
ha-map card with card_size: 8.65;
stock map card.

After resizing the window:

A height of ha-map card is ~452px and it seems to be constant: https://github.com/nathan-gs/ha-map-card/blob/e72bfb131835983ed9c3ee5a637da8a70d29ebb8/src/configs/MapConfig.js#L122

Is it possible to provide smth like

card_size: auto

possible value (and may be even make it a default value) to set "height = width" to get a square card? Ofc a "title is defined" case should be considered as well.
