Implements a new method `epic_disp_print_adv()` and improves
`display.print()` with new font parameter.

`epic_disp_print_adv()` behaves like `epic_disp_print()` but also takes
a new font parameter which is a number to select the font.  The font
name is verbalized using a new enum `disp_font_name`. The enum names
correlate to the fonts under gfx/fonts.  On the MicroPython side, in the
display module, constants are defined in order to provide names instead
of numbers.

Previously, race-conditions between multiple serial writes could lead to
memory corruption and weird artifacts like I2C getting stuck.  This
patch introduces a write-streambuffer which queues all messages.
