Background

Once the #2489 is implemented, we should add the ability to download the image that is shown at the moment for the user in the preview pop-up.

Approach

Add the download button to the HCS preview form, e.g.:

By click this button, the displayed image (corresponding to the selected plate, the selected well, etc., i.e. loaded at the preview form at the moment) shall be automatically downloaded to the local workstation:

• file should be downloaded according to the set zoom and channel filters
• file name shall include well and field info
• file shall have PNG format
