New feature: I18N compliant compact mode

[sandronm]

Hello!

First of all, thank you for your plugin!

I open this issue to ask you a new feature: be able to translate the text in the compact mode.
Right now, this possibility doesn't exist, in compact mode, the text is always "x values".

Thank you! :-)

Hi @sandronm,

This feature is currently work in progress :) I have updated the web component with a compact mode value renderer which enables adding a function to handle the "compact mode" display label (gatanaso/multiselect-combo-box#59). However, I have not yet released a new version or have added the appropriate API to the Java component.

Great news, thank you for your job!
