Allow for growing original icon set

[why]
We have an automation for adding glyphs to the original set.
If someone throws in the svg file and adds the glyph to the icons.tsv a
new original-source font is generated.

But the added glyphs are not patched in, because that would need a
change at font-patcher (adjust the end codepoint).

This can be forgotten easily.

[how]
The maximum codepoint of our own (original + seti) set is 0xE6FF. At
0xE700 the Devicons start.

The original-source generation script now checks the offset, they may
not be negative and on the positive end we may not leave our set-range.
If that happens the script fails thus the workflow fails.

Also increate the patch range in font-patcher. If there are no icons to
patch in the symbol font the codepoints are just ignored.
