typicons font to LVGL and HASPmota

[s-hadinger]

Description:

LVGL improvements:

• Add typicons font containing free simple icons for nice user interfaces. Icon browser is here: https://www.s-ings.com/typicons/
• Embed typicons-24 in LVGL pre-compiled binary, and provide 36/48/64 font sizes as optional .lvfont files to be placed in the filesystem

Also;

• Fix small glitch in wifi icon
• Add simple battery indicator to HASPmota demo using typicons font. It is currenlty a mock, hardcoded to the "charging" icon, but will evolve to refelct battery status
