[frameit] add font_size parameter

Motivation and Context

frameit scales the keyword and title automatically per screenshot to fit the available size above or below the device. This is a good approach for simple screenshots, but lacks a consistent and unified appearance across the screenshots.

Specifying a fixed font_size for keyword and title (separately) gives users of frameit the ability to fix the font size and keep it consistent across screenshots.

Description

This PR introdocudes a new parameter font_size for the keyword and title parameters. Instead of calculating the actual_font_size from the available space everywhere, it now checks for the font_size and returns it if specified and font_size > 0. This way, we keep the old behavior intact.

Testing Steps

Specifiy a font_size in either the default config in your Framefile.json or for a single screenshot config for the title or keyword. Frameit should use this font size when generating the framed screenshots.

Great addition, although a bit scary. Sure this will not change existing behavior?

The code now checks (see below), if a font_size is configured for either keyword or title and only if it does, it returns that. If not, the old implementation continues. So yes, I'm sure this does not change existing behavior.

       font_size = @config[key.to_s]['font_size']
       return font_size if !font_size.nil? && font_size > 0
