Log Message:
-----------
[E_B_D_T_] don't let sanitised glyph names collide

Dropping the directory part of a glyph name keeps the export inside the
bitmaps folder, but maps distinct names onto one file: "a/b" and "b" both
wrote strike0/b.bin, the second silently overwriting the first, and both
extfileimagedata entries then pointed at the same image. Before, such a name
raised FileNotFoundError, so this traded a crash for silent corruption.

Escape such names URL-style instead, with a leading '%' so an escaped name
can never collide with a plain one -- avoiding separators is not enough when
a real glyph can be named like another name's escaped form. Normal glyph
names contain no separator and no '%' and are kept as-is, so existing
exports keep their filenames.
