- added support for GDEM029T94 128x296 b/w e-paper panel
- added support for GDEW026M01 152x296 b/w new DES e-paper panel
- the new GDEW026M01 DES b/w e-paper panel has higher contrast and wide temperature range
- differential refresh (fast partial update) is supported for normal temperature range
- disable differential refresh for extended temperatures by setting hasFastPartialUpdate = false;
- the differential waveform table for GDEW026M01 is experimental and may need improvement
- major update of display selection in the examples to make additions easier:
- old style selection is now in separate include files GxEPD2_display_selection.h
- and GxEPD2_display_selection_added.h
- added new style display selection in include file GxEPD2_display_selection_new_style.h
- either selection style can be used. old style is intended for easy copying of constructor lines.
