Add feature: Support for two new display modes.
Two New Display Option:

• lcd35 - Using framebuffer copy (fbcp service) for the LCD35-show (3.5" RPi Display) from https://github.com/goodtft/LCD-show
• browser_only - For browser only access

Approach:

• Dumb display through framebuffer copy
• 3.5" RPi Display is not an EPD, so, didn't add/adjust too much code which may not be used in the future. Add basics only.
• Simple pass for methods which might be used.

Others:

• Added custom check for lcd35 display, and install the frambuffer imageviewer (fbi) dependency accordingly.
• Added method to calculate x-pos for left position for any image.
• Adjusted right border for frise and added thick line based on height of frise, this is so that image generated is centered or symmetrical.
• Image generation width adjusted to 3:4 aspect ratio, but did not use LCD35 resolution to not consume more memory. small image, small memory consumption.

The piwheel is the issue.

Good day @SgtStarSlayer!

This is not an issue directly related to the changes made. From time-to-time, dependency install will hit a snag due to items not under control or related to the code. You will see this several times in the issues submitted for this github repo.

You can simply choose retry from the option presented, or if you have exited of that, you can run sudo ./install_bjorn.sh again choosing the full installation until everything completes - usually a reboot is required when everything completes.
